The tree itself has a very beautiful drawing and pleasant appearance. But, as they say, there is no limit to perfection, and for for a long time We have been able to invent many ways to give wood interesting visual characteristics. One of the ways to give wood an unusual appearance is to roast it. It would seem that a tree is afraid of fire, and it is not very rational to subject it to this test. But, if you do everything correctly, the result is an extremely attractive surface, well wooden product at the same time it is not damaged and does not lose its performance characteristics, while acquiring many new qualities.
In fact, we are not talking about something new, since in Japan such wood processing has been known for a very long time - since the 18th century. Wood burned in this way not only becomes more interesting visually - changing color and showing texture, but also receives protection from fire, as well as insects, which are a scourge wooden buildings and products. Finally, the service life of such wood is also greatly increased, and it can last up to 80 years. Add to this protection against fungus and rot and you get one of the the best ways wood processing, which also does not require any third-party chemical components and is completely environmentally friendly.
Wooden components fired in this way are used in different areas, however, they are most actively used for cladding buildings.
What processes occur when wood is fired?
First of all, this is the strengthening of the top layer of wood during the pyrolysis process. Resins and carbon released from high temperatures, which appear during the combustion process, clog the wood fiber channels, narrowing them and making the wood less permeable.
How wood was burned before and how it is done now
As we said above, the process of burning wood has been known for a very long time. And not only in Japan, but also in other countries of the world. It appeared, most likely, by accident, since at one point people noticed that burnt boards had qualities that their ordinary counterparts simply could not boast of. This process was also known in Rus', where it was called “smoking.”
If earlier a fire was used to burn boards, which was very inconvenient, since the process was difficult to control, now, with the help of a conventional gas burner, the quality of the final product has become much higher. At the same time, we are not talking about some incredible complex technology, which is inaccessible to the vast majority of us. If you follow the rules, the process happens quite quickly, and the result is very interesting.
How wood is burned in industry
There is such a method as full firing. In this case, the boards are placed in an oven where the temperature reaches 400 degrees Celsius. In this case, temperature treatment occurs in vacuum conditions, which allows you to achieve the desired effect. This method is used for large volumes of products, and similar equipment for ordinary person it can not be. And wood still loses a number of its qualities.
There is also deep processing, during which the wood burns up to 20 millimeters, but, surprisingly, does not lose its properties. However, for such an activity you still need a stove, and the wood itself becomes not very interesting in appearance due to too much charring.
Self-firing - basic rules
- When starting work in the direction of firing, it is better to practice on unnecessary wood scraps. This way you can properly dose the effort without causing excessive damage to the wood. This is especially important if furniture firing is being prepared. After all, if the same board is damaged in the process, then you can take another one for finishing. This move doesn’t work with furniture; you can simply ruin an expensive product;
- Pay attention to the burner itself. Clean it well from soot. Otherwise, you will not be able to get an even blue flame, since it will be changed by combustion products;
- When firing, the upper part of the flame is most effective. Can you remember school lessons where you were told that the top of the fire has the most high temperature. It is she who needs to process the wood, otherwise the effect will be very far from ideal;
- The wood itself must be cleaned and properly sanded before processing. This is especially true for old boards that have lost their originality over time. this type, and the drawing on which has become dull. In this case upper layer you can even remove it, opening access to fresher wood, which, when pyrolyzed, will better reveal its design.
- If you want to achieve deeper burning of wood, you need to saturate it before work. copper sulfate and wait for the latter to dry completely. IN soft types wood vitriol will be absorbed deeper, therefore they will burn deeper;
- After finishing the procedure, go over the wood with a wire brush, and then soak it with a dark antiseptic. The next stage will be grinding followed by impregnation with a light antiseptic composition. As you scrape away the soot layer, a distinct woody structure will be revealed;
- You should not fire wood that has previously been treated with drying oil or putty. In this case, these materials will appear in the form of ugly spots, which will completely cancel out the positive visual effect from such processing;
- You can also reveal the wood pattern after firing by painting the surface and then removing the paint. Thus, the latter will remain only in the depressions previously expressed by pyrolysis. The main thing here is to choose the right colors. The ideal solution will become paint color Ivory. In this case, it is better to select acrylic paint, and it must be applied to a surface that has been previously cleaned of combustion products. Other visual effects can be achieved using varnish and technical wax.
Where else is wood burning used?
In addition to giving an interesting appearance and a host of new qualities to the façade elements, interior decoration and furniture, firing is often used for various wood elements that will be in the ground.
A striking example in this case is wooden fence or pillars. Of course you can process them special compounds, which are currently available in abundance on the market. However, the ability to resist moisture, insects and not rot can be achieved by simply placing it in a fire. In this case, a better effect can be achieved if the firing is carried out slightly above the level that will be in the ground.
IN modern construction Wood is usually treated with chemicals. But before, houses were built from wood, and some of them still stand to this day. We invite you to get acquainted with the method of processing wood by firing and find out what the advantage of this method is.
How does firing affect wood?
As the subcortical layers of the tree grow, year after year, its fibrous cells die off due to the formation of pores. High porosity, in particular, explains the hygroscopicity of wood - its ability to absorb and release water molecules depending on the difference between its own humidity and the content of water vapor in the surrounding air.
The structure of wood fibers is always uneven: in the process of life, cellulose polymers of varying degrees of stability, as well as sugars and resins of all kinds, are formed in wood. It is the presence of pores and organic nutrient residues that cause the main disadvantages of wood: flammability and the presence of a nutrient medium for the development of bacteria and fungi.
The opportunity to “seal” wood from the influences of the outside world still exists. It is used during creosote boiling of wood or during autoclave heating (thermolysis). When heated to 300-400 °C, almost all unstable hemicellulose formations are destroyed, and they serve as both a “launching pad” for the ignition of wood (forming the primary volume of flammable pyrolysis gases) and the initial breeding ground for the development of colonies of harmful organisms.
It is incredibly difficult to reproduce such wood processing at home. But it is quite possible to partially clog the internal pores and remove most of the unstable cellulose polymers. Even surface firing can heat the outer layer (5-20 mm) of wood enough to melt lignin and resins and form an inorganic crust that protects against most external influences. After proper firing, it is almost impossible to re-ignite the wood without intense and prolonged heating to 500-700 °C. In this case, the residual heat kills microorganisms remaining in the thickness of the wood, and the sintered outer layer prevents the penetration of pathogenic organic matter from the outside.
Decorative value of burnt wood
Much more interesting is the visual effect of burning wood. It was thanks to him that processing technology was born in Japan. wooden beams under the fancy name “Shu-Sugi-Ban”, and the meticulousness of the Japanese to the interior design of their homes is well known to everyone.
The appearance of wood processed in this way directly depends on the technique and depth of firing, and there are three types. The first - surface firing - allows you to create a brown-brown surface with a golden sheen, on which the wood texture appears quite contrastingly. The chemical and biological resistance of such wood is not high enough, so surface-fired products are used, as a rule, in interior decoration. Due to the fact that the impact on the wood structure is minimal, since firing affects only 2-5 mm below the surface, Decoration Materials can retain their lightness, that is, it is quite possible to process ordinary lining in this way.
Deep firing of wood is used for older lumber, often for boards and beams that have already been in use. This technique helps to “renew” the wood: remove the dried out surface gray layer and efficiently heat the entire thickness of the wood. Due to this, the surface acquires a very expressive appearance: from iridescent graphite to coal-black imitation of rare noble rocks. Perhaps, such a depth of black color cannot be achieved by other methods, which is why deep-fired wood is so highly valued by designers.
The third stage of wood processing is its complete burning. Actually, it ceases to be a tree at all, turning, in fact, into polymer-carbon plastic. At home, unfortunately, complete firing is almost impossible: during charring, the fire will have time to eat almost half the thickness of the workpiece. This wood is used primarily in the production of furniture. The technique guarantees the absolute uniqueness of each product, because the characteristic pattern and the resulting splits cannot be reproduced in any way.
What species and what type of wood is best to burn?
Generally any wood is suitable for firing, but connoisseurs of subtle visual delights will most like species with an expressive and unusual texture. The original technology of Japanese origin initially used exclusively cedar. Interesting view has burnt hornbeam and beech boards: due to high density Only the top layer of such wood burns through, resulting in anthracite and gray tints of color.
More popular valuable species, such as alder, maple and poplar, exhibit an elongated texture after firing, and walnut or larch can form additional finer textured patterns. Burnt birch will be highly appreciated by bath or sauna lovers: due to firing, its surface becomes very porous and acquires a low heat capacity, so after heating it does not burn the skin.
It is also surprising that, depending on the degree of firing and the origin of the wood, even the same species can manifest itself in completely different ways. To the use of burnt wood in decorative finishing you should take a thorough approach: stock up on samples different types from different sources and, after a series of experiments, come to a certain choice.
Remember also that the wood must be properly prepared before firing. It should have low humidity, preferably no more than 12-13%, and also be natural, that is, without traces of painting or opening with drying oil. Otherwise, the absorbed resinous substances will appear unevenly on the surface and disrupt the appearance. Of course, a lot here depends on the depth and time of fire treatment.
Charcoal firing in the field
The simplest method of fire treatment is best suited for deep firing. Processed this way decorative beams, and wood siding and a block house for exterior finishing. Due to deep heating, the wood becomes impervious to atmospheric influences, and the influence sunlight It doesn't affect her at all.
For charcoal firing, dig a narrow trench about 30 cm deep and a width corresponding to the size of the parts being processed. A fire is built in a ditch, and as it burns, the wood is constantly stirred, achieving rapid charring. After this, the ditch must be covered either sheet iron, or a strip of OSB to temporarily prevent the access of oxygen and stop combustion.
Before laying the workpiece in the coals, you need to rake out the central furrow so that during firing, not only the lower part, but also small areas on the sides are processed. The holding time of the workpiece depends on the thickness and can range from two to three to fifteen minutes. After this, the workpiece is turned over to the opposite side, and then, after maintaining the same period of time, it is burned on the sides.
It will be easier to remove the workpiece with a pair of steel wire hooks. After the wood is removed from the coals, it is immediately doused with water.
How to burn wood with a gas torch
Using gas burners is much easier. These can be either hand-held camping lamps or regular nozzles connected to the cylinder via a hose.
It is convenient to process wood with gas only by surface firing. Deeper aging in the fire will not be sufficiently uniform, as a result the product may have variable thickness and width. In addition, deep heating will require quite a lot of gas, while coals cost almost nothing.
When surface processing the wood, the very edge of the light blue torch is touched. The movements are roughly the same as when painting. At the same time, it is quite easy to control the firing depth based on the degree of darkening.
Firing is followed by wetting, but in this case an ordinary hand sprayer will suffice. It is important that the time interval between fire treatment and water spraying is the same for all areas of each part, so carry out the treatment sequentially.
Finishing of burnt wood
After the wood has cooled, soot and soot are removed from it. For this purpose, brushes made of brass wire are used so as not to strip off excess. During machining Invoicing or so-called artificial aging wood
Cleaned products can be installed immediately. Additional processing is needed not so much to protect the structure of the wood, but to preserve its color and overall appearance after years, as well as to eliminate soiling. For interior decoration, the lining is coated with linseed or hemp oil in several layers. Wood for facade and others external works Coat 1-2 times with colorless nitrocellulose varnish with the addition of synthetic wax: either with a brush along the grain or with a spray gun.
Despite a century with advanced technologies and progress in development, wooden housing is more relevant than ever. They are also successful various elements wood decor.
One of the latest innovations is wood firing, which fits well into a wide variety of interior designs. At first glance, some might say that this technology somewhat awkward. However, due to its uniqueness and originality, it is used quite successfully and continues to gain popularity year after year.
Benefits of technology for the average consumer
Despite the fact that in European countries and, for example, in Japan, this original technology has been known for a long time, in Russia they learned about it relatively recently.
It is worth noting that it is quickly gaining popularity in the line of extraordinary arrangements such as interior design, and with exterior decoration and there are many reasons for this:
The surprising thing is that when firing, you can paint wood in various unique shades, and for example, with the help of paints, if these results can be achieved, they can only be achieved at great expense and with the help of specialists.
What is the firing technology based on?
There are three principles of burning wood:
- Surface treatment.
- Full.
- Deep.
Full processing is more suitable for large-scale volumes. To carry it out, the wood is loaded into vacuum ovens, the temperature in which is very high and sometimes reaches 400 degrees.
It should be immediately noted that this technology is rare, since due to the influence of such high temperatures, any tree loses its original strength.
As for the other processing option, deep, it is carried out in open ovens. The wood is burned in these ovens for some time and then extinguished under the pressure of water. What is characteristic is that with this method, burning of the material up to 20 mm is allowed and despite this, it remains as strong as initially.
There is also a negative side to this case. Since this technique does not create a very presentable appearance, it is used quite rarely.
As for the third option, it is rightfully one of the most popular, especially among home use. For example, it is used to burn furniture and other interior parts.
This type of wood processing is carried out using a regular spray can with a special nozzle, or a blowtorch. On average, the burning depth does not exceed 4 mm and after the procedure the wood is sanded, as a result of which the final result acquires not only beautiful textured outlines, but also resistance and durability.
Firing at home
Burning wood is not a difficult procedure, even if done at home:
To begin with, the wood is thoroughly prepared for the process. To do this, remove the surface of the material from excess moisture and dust and sand it.
You need to check the wood especially carefully for moisture, since due to excess moisture, the material may become covered with spots and stripes during the firing procedure and, accordingly, lose some of its attractive appearance and strength.
It is best to work with material that has just been processed and has retained its texture pattern and color patterns. If it has already darkened, it is recommended to treat it again with a plane or sandpaper.
Important! You cannot use any wood for firing that has been finished with materials such as drying oil and putty. The fact is that when heated, these materials contribute to the appearance of stains with a dirty tint, and the natural layers of wood and texture patterns are simply not defined.
Before starting the procedure, the burner must be adjusted until the flame itself becomes bluish and oblong.
If soot has accumulated in it, then the flame will be uneven with a yellowish tint and, because of this, the firing procedure will become unproductive.
It is necessary to understand that it is not the flame itself, but only its tip that contributes to the necessary firing. Because it is the only one with the highest temperature. Professionals in this field strongly recommend that beginners not endanger furniture structures until the necessary skills have been developed. various scraps. Firstly, you can slowly set up the burner, and secondly, you can gain the necessary experience.
Rules for firing furniture
When you want something new, but either don’t have the funds for it, or just want to do it yourself, then charred wood in the interior is the most best option choice. For example, if you have unnecessary furniture lying around your house or closet, like a chest of drawers, you can decorate it yourself in this original way.
For this procedure you will need:
- Acrylic paint with brush.
- Firing tool. For example a burner.
- Metal brush.
- Grinding machine.
- The required number of bronze-coated handles.
- The chest of drawers itself is made of pine.
To begin with, after setting up the burner, the entire surface is fired. After this, you need to carefully get rid of the resulting soot using a grinding machine and a metal brush.
Due to the fact that pine has both hard and soft fibers, during processing a fairly presentable and unique pattern on the relief is achieved.
The next stage is getting rid of dust, after which the chest of drawers is painted acrylic paint, but in principle you can use any other one, for example CC or a latex analogue.
A wide variety of color solutions can be chosen, but if we start with the ones that are most suitable specifically for pine, then we should focus on ivory and paint should be applied strictly along the existing fibers. Otherwise, there is a high probability that some relief parts of the surface will simply not be painted.
After this, you should wait until the paint is absorbed and dry, and then sand the surface again with a sanding machine, due to which the applied paint will remain only in the formed recesses.
In order to reveal the structure of the wood on the material, it should be sanded slowly and delicately.
Finally, you should equip the chest of drawers with handles. In tinted bronze, this type of decor will definitely make the chest of drawers stand out from any other furniture in the interior.
How to make burnt wood original
In order to make the product more attractive in appearance, before applying varnish to it, it can be slightly shaded using aniline dye.
There are plenty of options for such decor. For example, for a matte shade, you should add to the varnish before application. a small amount of special color wax based.
Don't be confused! In no case should you use natural wax for this treatment, since it will not lose its sticky properties after processing. Before adding technical wax to the varnish, it is dissolved in turpentine heated to 40-45 degrees.
In total, wood treated with varnish and fire becomes, first of all, durable and at the same time beautiful and original.
If the façade is finished in this way, then its minimum service life is from 4 to 6 years, and when finishing interior items it is within 9-12.
Video: burning wood in the interior
Everyone knows that wood cannot be left to its own devices - under the influence external forces it quickly collapses. Impregnation with antiseptics and fire retardants is required. But there is another effective protection, without the use of "chemistry"
Many centuries ago, our ancestors noticed that if you burn a piece of wood a little, it will become stronger. This technique, called Shou Sugi Ban (“cedar languishing”), is believed to have originated in Japan. Although there is quite reliable evidence that wood was processed this way on all continents, including ours. In Rus', pile pillars, joists, floorboards, wall cladding and roofing were protected by firing (smoking).
Today ancient method heat treatment of wood is not only not forgotten, but is enjoying more and more popularity. The development of technology has made it possible to bring it to perfection. The wood is burned using a gas torch/blowtorch or kept in a kiln, resulting in a new, improved material.
Under the influence of high temperatures, all possible “seeds” of decay die. Wood sugar burns out, making the wood unappetizing to wood-boring beetles and other harmful microorganisms. The molten resin closes the pores of the material, making it less hygroscopic, or, in other words, in simple words, ceases to be “afraid” of water.
As strange as it may sound, charred wood becomes fireproof. It is almost impossible to re-ignite an already burnt board.
But that is not all. During the smoking process, the wood becomes amazingly beautiful. It darkens, becoming dark chocolate or impenetrable black, and acquires a noble silvery sheen that cannot be achieved by any paints.
Of course, so interesting characteristics attracted the attention of masters from various fields. Today, charred wood is used everywhere. It shows itself perfectly both in the decoration of houses (floorboards, wall cladding, ceilings, facades and roofs) and in landscape design(fences, pergolas, gazebos, greenhouses and even framing beds).
Another area of application is furniture industry. The exquisite black color with a pearlescent sheen has made Shou Sugi Ban wood a favorite material for designers creating luxury interior items.
Types of firing
Previously, wood was simply thrown into a fire or kept in primitive ovens. Today, with the help of modern equipment, it is possible to regulate the processing temperature and achieve certain effects.
Firing options
The most popular firing is surface . It involves processing gas burner or blowtorch. The depth of thermal impact in this case ranges from 1 to 5 mm.
Deep firing produced in an open oven, providing processing of a layer up to 20 mm thick. At the same time, the lumber is not only hardened, but also acquires a deep black color with a graphite tint.
Full firing produced in industrial vacuum furnaces at temperatures up to 400ºС. This technology is used quite rarely, since the wood dries out very much and becomes too dense, and therefore prone to splitting. The main area of application of this material is the production of luxury designer furniture.
How to choose the type of wood for firing?
Initially, Shou Sugi Ban intended to use only and exclusively cedar. Today, you can burn almost anything, the only question is what effect you want to achieve. Yes, on soft coniferous varieties(pine, spruce, etc.) a clear, large grain pattern appears. Beech, hornbeam, walnut, maple and other dense species acquire a homogeneous dark color with a silvery coating. And larch and walnut will surprise you with their whimsical small pattern surfaces.
Burning wood over a simple open fire is ineffective - the material becomes coated with too thick a layer of soot
Firing technology
The main advantage of Shou Sugi Ban technology is its accessibility. Almost anyone can do this job. A gas torch or blowtorch and at least a little experience with these tools are enough.
But before you start firing, the wood needs to be prepared. The surface must be smooth and clean. If there are marks on the board old paint, oils and other contaminants, they must be removed, otherwise after heat treatment they will turn into indelible stains.
It is very important to check the moisture content of the wood. The moisture concentration in the material should not exceed 13-15%, otherwise, after firing, spots and stains will appear on the surface of the board.
Freshly planed wood is best suited for firing. If the material has been stored for a long time, has darkened and become porous, it must be sanded before heat treatment.
When processing, the boards are touched with the edge of the torch, holding it perpendicular to the surface. It is very important to ensure that the wood chars evenly, that is, the change in tone is uniform along the entire length of the board.
After firing, the surface is moistened with water from a spray bottle, wiped dry, and after the wood has completely cooled, the carbon deposits are removed with a brush. If you take a tool with metal bristles rather than synthetic ones, you can at the same time age (brush) the wood, making its texture clearer and more expressive.
As mentioned above, burnt wood does not need to be impregnated with any protective agents. But if you want to maximize the life of a material that is used in harsh conditions (for example, on facades), you can resort to “chemistry”. There are quite a few options: linseed and hemp oil, nitrocellulose or urea-formaldehyde varnish, synthetic wax. But the easiest way is to buy it in hardware store a special oil-wax composition for impregnating wood.
Burnt wood retains its strength and attractive appearance for 80 years or more. It does not require tedious care. You only need to clean the surface occasionally and renew the impregnation every 3-4 years, if any.
Processing wood by firing makes it possible to obtain wood with a more pronounced structure, and the material becomes less susceptible to burning, rotting, damage by insects and ultraviolet radiation. That is, both aesthetically and practically.
We invite you to talk about why wood is fired, what can be used to burn it, what kind of wood to take for this and how to treat it after firing.
Wood burning: why do it?
Today, the most common way to protect wood from external factors is chemicals– , all kinds of impregnations. But chemistry is chemistry, and people often have a desire to process wood without using, in fact, poisons. One of these methods is wood burning.
The essence of firing is that under the influence high temperature In the outer layer of wood, during pyrolysis, the fiber channels become narrowed and clogged with combustion products and resins. Thanks to this, the top layer of wood is compacted and becomes almost inaccessible to fire, fungi, mold, insects, and sunlight.
The resulting charred layer, of course, needs to be removed. For small crafts, this is done manually with metal hard brushes; for larger ones, special attachments for grinders or drills are used. And here the second one opens pleasant wood firing quality: aged wood effect. In fact, burning wood followed by cleaning it with brushes is, that is, artificial aging of wood. And although firing is not a mandatory component of the brushing process, many craftsmen resort to it.
As a result, all kinds of boxes, picture frames, panels can be made from such wood, used in construction as logs, facade boards, beams, platbands, windows and doors, material for the manufacture of wells, toilets, dog kennels, gazebos, etc. In the latter case burning the wood with a gas burner must be carried out before assembling the structure. Firstly, burning a house is not safe, and extinguishing a fire, if one happens, will not be so easy. Secondly, it is not convenient to carry out subsequent cleaning of burnt wood on an already finished structure. You will spend a lot of effort, but you won’t be able to carefully scrape off the burnt layers, especially at the junctions of wood elements.
Burning wood: which wood to use?
As for the quality of wood, this is a rare case when the third grade is not a defect, but what we need. When soft charred fibers are brushed out after burning wood, depressions form in their place, and harder layers turn into ridges. This is the only way to get textured, relief, contrasting material. To do this, you need to choose a workpiece with: knots, curls, eyes, curls (but if we're talking about about wood for construction work, then beauty can be sacrificed here).
There is no need to pre-sand or prepare the board in any way - firing will remove all imperfections, and decorative properties wood is given after firing.
Although you can burn not only raw wood. For example, if you have a chair, table or fence covered with stain, and you would like to emphasize the texture of the wood, which is “eaten up” by the impregnation, wood burning also appropriate. Moreover, not only wood, but also chipboard can be fired. Let us remind you that they are subjected to firing conifers wood, so even the veneer should be pine, spruce, etc.
Wood burning technology
Before, how to burn wood, take precautions. After all, you will be working with open fire. Suitable for small bars for crafts open balcony, but with full-fledged boards it is better to work in the open air.
You can burn wood:
- gas burner
- gasoline-powered blowtorch
- ordinary gas cylinder with nozzle
- construction hairdryer
Those who burn and brush wood on a small scale for crafts have long fallen in love with the Dremel. It is small, convenient, and in the household, a “mini-drill” is useful not only for burning wood.
In addition to wood and a burner, for firing we will need a hard brush and a soft wide brush for sweeping away the burnt residue (flutes).
A brush with metal bristles is suitable for cleaning small bars. For large-scale work, it is better to arm yourself with a grinder, drill or grinder with special attachments
1. Direct burning of wood
Calmly and evenly move the burner over the wood so that there are no charred or “under-burned” areas.
You can choose the degree of firing solely according to your taste. If the firing is weak, you can then go through the burner again; if you fry it too much, you will just have to work harder to remove the carbon deposits, the pattern will be more contrasting. The main thing is uniformity of firing.
If your wood is not, it will almost certainly contain either drips or resin pockets which may catch fire. Put out the fire immediately, otherwise an unsightly dark stain will form in this place. Firing one standard board will take up to 10 minutes.
2. Scraping out sawdust
We take a hard metal brush - the kind used to remove paint - and begin to move it exclusively along the fibers. Instead of a brush, you can use a brush grinder, drill or grinder with special attachments. This way you will “stir up” burnt out soft fabrics in the hollows of wood. After practicing a little with the brush, take the flake and take it out, knock it out, pick out the sawdust. This needs to be done “against the lint”, otherwise these dust particles will simply get deeper into the cavities.
Brushing wood after firing with a brush sander
3. We bring it to the desired state
Alternating between a brush and a brush, scrape down the wood grain-by-grain with strong, long strokes. You cannot brush the brush perpendicular to the grain - the hard bristles will leave a mark and ruin the entire pattern. When to stop is up to you to decide, based on your aesthetic preferences. By firing wood and brushing, you can obtain material from gray, charcoal black to chocolate brown and golden shades.
Wood burning: what's next?
In general, you can stop at burning wood, and continue gluing, building, cutting... This is a full-fledged construction and decorative material. Firing wood allows you to get an original shade that cannot be achieved with any basic paints and varnishes.
To give wood a glossy shine, you can treat it with all kinds of high-quality oil impregnations, or tinted with primer, enamels, glaze, coated with wax and wax varnishes.
