The use of Japanese woodworking dates back to the 18th century. During that period in a large number they burned the Sugi cypresses, which were the source of fires on the islands. Looking at the sight of a charred tree local population became interested in the properties of the material obtained. After that, the Japanese began to widely use this practice of roasting. This technology is called Yakisugi, which means “cedar languor”.

In Japan, among soft species, cedar is widely used in construction works... Such processing of wood with fire allows the texture to appear, and also eliminates the problems of rotting, burning in fires, and insect damage. In addition, the shelf life of the material is extended to several tens of years, and therefore it is used for facade works, construction of fences and wall decoration.

However, these processing technologies wood material are ancient, they were used by almost all peoples and tribes. The firing method and the use of hot resin for impregnation are very common. Their advantage is that the channels between the fibers become smaller and filled with resin, protecting inner part logs from negative impact physical factors.

An outer crust up to 0.5 cm thick is formed, which protects the inner layers of the logs. If earlier a fire was used for burning, today they use a burner fire or blowtorch... The method is suitable for the treatment of soft conifers, which are known for their hardiness and high oil content. These include pines, cedars, spruces, etc. Such forests are common in all regions of Russia, which is why the method is also known in these places.

Burnt wood properties

Japanese technology of wood processing by fire gives the material a deep gray tint, unusual reflections of gray hair and surface irregularities. Japanese longing differs from other types of roasting: the material can be soaked with oils once every 4 years, painted and various decorative compositions can be applied to it. Although there are few people who want to change color, the resulting color is unusual and deep. By doing this, the service life of the material is extended.

Japanese craftsmen are very careful about nature and themselves, so they try to do without chemicals. Their method does a good job of antiseptics or fire retardants. In addition, fired material burns more slowly than unfired material, which is its advantage.

Woodworking is carried out as follows: parts are prepared from a material rich in resins, firing is carried out using a burner for 10 minutes, then immersed in water for rinsing. After washing with a wire brush, the surface is cleaned from excessive roughness and carbon deposits. After all these measures, a thin charred layer remains, which can protect against moisture, microorganisms, insects, protozoa and fire.

Stewed cedar finish

After firing, the wood is used immediately, or it is still impregnated with oil. Homes finished with this method are found everywhere in Japan, which proves their strength and durability. The appearance of such houses is distinguished by a peculiar iridescent shade of gray, which cannot be achieved by mixing different colors... The range of shades of charred cover depends on the firing time: from silver, brown to black. The resulting material is used not only when working with the facade, but also in the manufacture of furniture and other accessories for interior decoration.

You don't have to travel to the East to learn how to burn properly in Japanese. The method is simple, so you can watch a video that clearly shows the stages of the procedure, and independently test the technology, observing the fire safety rules. However, at home, the method is difficult to reproduce, since it is necessary to clog the pores and eliminate uneven polymers. If firing has been carried out correctly, it will not be possible to reignite the material. And the formed residual heat will kill insects, bacteria and fungi located in the thickness of the wood, the outer layer will not allow them to penetrate into the thickness. The resulting wood can last 80 years after processing, while not requiring special care or biological treatment.

Yakisugi - Japanese wood processing technology"Languishing cedar" Is a Japanese technology for treating wood surfaces using fire. This simple process allows not only to show the texture of the wood, but also protects it from fire, decay and insects. The service life of such wood is increased to 80 years, therefore it is used for facing the facades of houses and building fences.
The story began in the 18th century with a massive burning for the purpose of fire protection plots of Japanese cypress "Sugi" densely enclosing Japanese villages. After some time, the residents understand that the burnt cypress wood is beautifully protected and amazing in beauty, the Japanese began to use it everywhere in construction.

But in fact, wood burning was used by almost all peoples, since in ancient times, along with resinification (impregnation of wood with hot resin), burning was itself a common way to protect wood from decay. The fact is that under the influence of high temperature in the process of pyrolysis in the outer layer of wood, the fiber channels narrow, they become clogged with resins and combustion products, which significantly strengthens upper layer wood and increases its service life. In the old days, an ordinary fire was used to burn wood. Very often logs, floorboards and roofing boards were burned. In Russia, this process was called "smoking".
The advantages of such wood after fire treatment:

Protected from fires
- Does not rot;
- Protected from insects and fungi;
- Easy to manufacture;
- Does not change appearance and color over time;
- Service life - up to 80 years.

Nowadays, a gas burner is most often used for burning wood. To achieve the desired effect, the resinous boards are folded into a triangular shape to form a box, and then fired for 7-10 minutes. The duration of the thermal effect affects the durability of the fired board and is determined by the type of wood, its moisture content, the thickness of the board and the desired effect from the structure and color. Then we extinguish the burning surface, clean it with iron brushes from ash residues and rinse running water. Ready! Now this wood can be used for facade cladding, track or fence

Burning wood is one of the simplest ways to decorate and protect the surface from a number of harmful effects. How to properly perform such an operation at home is described step by step in the article.

Who invented to burn wood?

According to one of the versions, it is considered that the Japanese were the first to start burning wood. At the same time, they used this technology, oddly enough, not on their products. Initially, in this way, they kept the forests from fire during the fire season. The burnt lower part of the barrel became difficult to ignite and, accordingly, was less exposed to fire.
The second popular legend also hails from Japan. If you believe this version, then one day the Japanese noticed that after a fire in the forest, charred trunks survived longer than those that passed the fire. In particular, they noted for themselves that burnt wood does not rot so quickly, and that insects do not grind it at all.
Later, this technology, prompted to people by nature itself, began to be used in construction. So, before installation, the roofing board was fired, wall beam, wooden piles. This made the building more durable, protected from insects and, in part, from fire.
Even later, firing began to be used for decorating wood products, in particular, for furniture operated on outdoors... The goal, in this case, was not only to protect the material from harmful effects, but also to give the surface an attractive appearance.
There is also a version that the Vikings began to burn wood long before the Japanese. They used this technology to craft their ships.

Benefits of charred wood

The advantages of wood treated with an open fire are as follows:

• presentable appearance;
• unattractiveness to insects;
• increased fire resistance;
• sealed surface;
• increased strength;
• improved moisture resistance;
• wear resistance;
• UV protection.

In addition, in the process of firing low-quality sawn timber, almost all defects are eliminated - darkening, blue, light rot. The processed product also does not require planing and finishing sanding.

Applying technology at home

In everyday life, the burning of lumber is used everywhere. The technology allows turning pine into rare wood without the use of stains, toners and oils. In particular, with deep roasting, which is described in this article, the most defective pine easily turns into wenge (it grows mainly in Africa).
It is especially useful to use firing in the manufacture of products and structures that will be used outdoors. It could be garden furniture, fence, gazebo. Also, fire often processes wooden elements of housing - sheathing, frontal boards, terraces, balusters of stairs and so on.
Burnt wooden boxes, gift cases, frames for pictures, grooves and photographs, various stands and lamps will look beautiful.

What kind of wood can be burned?

Not all wood can be protected and decorated in this way. First of all, this applies to fruit species, oak, ash and alder. However, the most common lumber - pine and Christmas tree - is perfectly fired. It is also possible to fire veneer and plywood.
For firing, it is best to choose a material on which an ornate structure is visible. During processing, softwood will burn out and be removed, and hard fibers will stand out more dark color... At the same time, knots, blue, fungus and other vices are not a problem for fire.
When firing coniferous wood, it is better to take dried material. It burns much faster, there is less resin in it, with which there will subsequently be certain problems. It is also quite possible to burn raw wood. However, it should be borne in mind that such processing will partially clog the pores of the material, and the moisture remaining inside will go out much longer, which is not good.

Firing tools and materials

The main tool in this business is a gas burner. Just an open fire ( gas stove, fire, etc.) does not fit well, and it will not work evenly to burn a large surface. It is also undesirable to use a gasoline blowtorch. It burns, of course, excellently, but droplets of unburned fuel can fly out of its nozzle, leaving shiny spots on the wood. Alternatively, you can try using a building hair dryer. But a lot of time is spent with it, and it will not be possible to achieve deep firing.
A gas burner is best suited for this business. Costs a penny, safe to use, easy to control and customize. You can even get by with the cheapest Chinese-made option, which, together with a can of gas, will cost about $ 5.

For large-scale work, it is better to get a large gas burner, which is designed for laying bituminous roof.
In addition to a source of directional fire, you will also need felt. In extreme cases, you can take a washcloth from the kitchen and use the harder side of it for work.
Basically, that's all it takes.

Phased wood burning. Nuances of technology.

Deep firing should start with a shallow burner pass over the material. At this stage, you need to evenly warm up the wood, burn out the protruding pile, and also open the places where in large quantities concentrated resin. These areas will need to be given special attention later.

Such places are clearly visible in the photo. As a rule, they appear on the knots, and after the first pass they do not darken, but are covered with boiling resin. It is highly flammable and can spoil the whole result, therefore the knots should be warmed up carefully. Warmed up, waited until it boils, then again. Repeat until boiling stops.

While the resin is boiling and the wood cools down in these places, the second stage is carried out in parallel - deep firing. The challenge is to make the surface char and crack slightly. The photo below clearly shows how it looks.

The next step is to remove soot from the surface. This can be done in several ways: using felt, a soft brush or special attachment for the grinder (brush for brushing). The only condition for all cases is that it is necessary to clean off the soot only in the direction of the wood grain.
Sandpaper is not suitable for these purposes. It is advisable to use it only for surface firing of wood. In this case, it is necessary to remove all burnt soft fibers, and sandpaper it will not cope with this task without scratches.

By the way, if you want the result to be lighter than in the above photographs, the surface needs to be brushed a little longer. But you can only achieve lighter shades with a brush. Felt will not be able to reach light wood.
Some craftsmen wash off the soot with water, which, in principle, gives a good result. But it should be borne in mind that dry wood, in direct contact with water, will take on a little moisture, which, in turn, can lead to deformations and other problems in the future. A more predictable result is obtained only on dry basis.
After firing, all that remains is to cover the wood protective compound... For a silky, matte finish that feels like clean wood, use special oils. Glossy surface, shimmering under the sun's rays and under different angles black to light vision - obtained after applying several coats of ordinary wood varnish.

Outcomes

In general, decorating the simplest pine tree using firing is not a complicated procedure that requires experience, expensive tools and compositions. The main thing is not to allow it long burning wood, completely evaporate the resin, achieve cracking and remove soot only in the direction of the grain.

Who among us does not dream of an eco-friendly home somewhere on the banks of a river, with birds chirping, and fresh air? One thing is alarming - it does not differ in durability. Sooner or later, traces of decay will make themselves felt. Natural wood recently popular as a material for manufacturing and decor items. Most often, industrially manufactured samples are processed with antibacterial, anti-mold, and fire-fighting compounds, which, alas, are not always distinguished by high environmental friendliness and safety. Is there an alternative? It turns out that everything was invented for us long ago - many centuries ago. The solution against aging and decay was prompted by nature itself: our ancestors noticed that a burnt tree retains its natural qualities longer. How to properly process wood at home, as well as the nuances of using this unusual technology, we will consider in detail in our today's review.

It would seem that it could be easier - buy varnish, process the wood and live in peace. But in the process of using any chemical compounds- imperceptibly, but, alas, constantly - can release a certain amount of compounds into the environment. Most often this occurs under the influence of temperatures, sunlight or. Not all Decoration Materials equally well amenable to chemical treatment. However, the tree is perfect option to use direct firing technology. How it works? During controlled heating, processes begin in the outer layer of the wood that stimulate the narrowing of the fibers, and the outer "pores" of the wood are closed with resin and soot. Thanks to this, the top layer of wood becomes invulnerable to negative impact. environment, the ingress of bacteria, and sun rays... Plus, it really looks very pretty.

Among the many ways to protect wooden products from the impact of negative factors, firing is considered the most in a convenient way which is easy to use at home.

Advice! Most often, gas burners are used for firing, and firing is carried out with special means extinguishing: a fire extinguisher and a bucket of sand. However, if you choose the right wood option, no excesses should arise.

In ancient times, no auxiliary tools were used. The necessary wood blanks were simply burned with torches, gradually turning the log on ropes or leather belts. Sometimes it was called roasting, sometimes languishing. The most commonly used were cedar, beech, maple, ash. After firing, the craftsmen removed the carbon deposits, washed the workpieces and soaked them in tung oil. In the process of processing, it was important not to burn the tree, but to singe it. If the technology was followed correctly, then as a result the tree received a unique shade, and its service life increased to 80 years.

Interesting fact! Until now, on the island of Naosami (Japan), burnt wood is used as the main building material. It is processed in a special way, the nuances of which are kept in the strictest secret... The technique is called Shou Sugi Ban, which means stewed cedar. Not only houses are built from processed wood, but it is also used to make furniture and decorative elements.

Now let's talk in more detail about the heat treatment options wooden structures... The result (shade, firing depth, characteristics) depends on the type of processing and the type of workpiece. Three types of firing are used for wood processing:

• Option number 1. Surface firing. One of the most commonly used types of processing. It does not require much time, special training and costs. Firing is usually carried out at home using gas burner or blowtorch. The maximum firing depth is approx. 5 mm.

• Option number 2. Complete firing. This type of wood processing is not available to everyone. The fact is that for such a firing it is necessary to ensure a sufficient temperature - about 400 ° C. It can only be achieved in special vacuum furnaces... It cannot be used on a large scale for processing building materials: the tree loses its volume by almost half. However, this type of wood processing is popular in the piece production of furniture and decorative items.

• Option number 3. Deep firing. This type of treatment is popular for the special aging of used wood. Usually this type of firing is used for decoration. The shades here depend on the exposure time - from graphite to coal black. Sometimes the wood processed in this way can be used for the device of special and garden paths... In this case, the firing depth can be up to 20 mm.

Advantages and disadvantages of technology

Wood processing at home has a number of indisputable advantages:

• no need to use complex chemical substances;
• the method, subject to the technology, is quite simple and can be implemented outside a special workshop;
• material acquires important properties: fire resistance, wear resistance, the tree is not affected by microorganisms;
• the process can be carried out without the help of third parties.

Interesting fact! Under influence high temperatures in wood, hemicellulose formations are destroyed, which, when burned, form flammable pyrolysis gases. Accordingly, after heat treatment the wood becomes resistant to fire.

Is it possible to carry out the firing procedure at home

As we mentioned above, wood processing at home is possible. However, one should adhere to certain rules and the exact algorithm for performing the work. These steps depend on the type of wood and the type of firing. Step by step we will deal with all the features and nuances of the preparatory work.

How to choose the type of wood for firing

Initially, back in the old days, cedar was mainly used for roasting. Over time, it was noticed that burnt beech wood and hornbeam have a similar texture and quality. The layers of wood of these two species have a high density, so mainly only the top layer burns here. But the poplar or maple familiar to us, after processing, get an interesting woody structure of lines elongated along the line. Conifers differ in a wide variety of patterns. After decorative processing tree, an unusual, unique structure appears. But the birch processed by fire after firing acquires a low heat capacity and practically does not burn the skin, which will be an additional bonus for decorating the walls of the shower room or in this style.

Stages of material preparation

If from the outside everything at first glance seems very simple - cut down a tree, walked with a blowtorch and that's it - then we are in a hurry to upset. First of all, you need to carefully select the material. The tree itself must be prepared for processing: remove branches, ideally, the workpieces should be dry and clean. If the wood is too wet, the moisture can deform the surface when it evaporates, creating unnecessary chips and cracks. One more essential requirement- if you are using old wood that was previously used, then varnish is also needed: all untreated chemicals will simply melt and leave an unnecessary trace, which will directly affect the quality of the finishing material.

Advice! It is best to sand the wood before processing. This will ensure uniform coloration. finished product after firing and grinding.

Blowing wood with a blowtorch

It is important to remember that wood processing should be carried out using the most heated tool. By analogy with construction hairdryer(which can also carry out this procedure), the blowtorch in the literal sense of the word should light up and warm up the nozzle. For proper firing, the fire must be directed strictly perpendicular to the surface to be treated. The exposure time here depends on the thickness of the workpiece itself and the goals that you are pursuing. The most important thing is to carry out the manipulations slowly and evenly, processing the entire surface, paying attention to the change in the structure of the material.

The surface should evenly acquire an even, contrasting pattern. Then the primary grinding of the product is carried out, as well as processing with varnish or drying oil.

Advice! If you don't heat the blowtorch to the highest possible temperature, you will end up with a layer of soot instead of the aged wood effect.

For convenience wooden board placed on stools in several rows. Moreover, it is better to lay out the boards in the same order in which their installation (if it is a facade) or fastening will be carried out. Processing is carried out sequentially for each.

Burning wood with a gas burner

Unlike a blowtorch, treatment with a gas torch has a number of nuances. It is most often used for surface treatment of wood. This is due to the fact that the flame of a gas burner penetrates deeper into the structure of the wood: with an increase in the exposure time, it will not be possible to achieve uniformity.

The most important thing is to strictly control your own movements so as not to overexpose the flame in one area to the detriment of another.

The technology requires mandatory wetting of wood after firing. Moreover, the period of time between firing and spraying from a spray gun should be the same. After cooling, the top layer is cleaned, the soot is removed either with a stiff brush or with a special brass wire.

Does burnt wood need additional protection?

Burnt wood itself has a number of undeniable advantage but he also needs protection. Most often, after the first stage of cleaning, the product is treated with oil. Usually a protective varnish is applied after that. And if the coating will be used to decorate the facade, use synthetic wax dissolved in turpentine. This will allow the wax to acquire additional bonding and protective properties.

Where is treated wood used?

Burnt wood has been very much appreciated by designers lately. You can buy interesting interior items made of burnt wood in art workshops or studios of modern designers.

The effect of using burnt wood in the interior

Wood is widely used to create furniture. It doesn't matter if it is a flat board, or raw wood: in any case, you will receive a unique piece of furniture, created with love., As well as wines, household utensils.

Sometimes even entire zones are trimmed with such panels. For example, a kitchen or a bedroom.

The nuances of using burnt wood in the design of facades

Burnt wood is used quite often. It gives the building a unique chic. If you think this is aging the room, you are wrong! Facade decoration can be quite avant-garde.

The possibilities of using the burnt board are wide. Treated wood shows very good "driving characteristics", it is widely used both for facade decoration buildings, and for interior decoration. The process itself, as we found out, is not so complicated, and the result is really impressive.
