To diversify the country menu, you can lay out a brick tandoor with your own hands, spending very little time on the device of this unusual stove. The design of the tandoor has historically developed among the steppe nomadic peoples, who were forced to conserve fuel. For heating such a hearth, very little firewood is required, after which you can bake bread or cook food in the heat that the heated walls give. In a dome-shaped oven, the desired temperature is maintained for quite a long time without fire, and if necessary, it can be maintained by adding wood chips or dry plant branches.

Currently, Asian hearths are one of the types of exotic stoves. Traditional ways making them from clay is quite complex and labor-intensive. Therefore, more and more often you can find country mini-ovens made of bricks. There are both electric and gas models industrial production.

But anyone who is a little familiar with the masonry technique can make a brick tandoor with their own hands. There are several varieties of homemade foci:

vertical square;
vertical cylindrical;
horizontal (Central Asian).

Cylindrical vertical models are especially popular. They are made both submerged in the ground, and ground, and even mobile. This design allows you to use the hearth for different purposes: bake cakes or samsa, fry barbecue, cook pilaf or other dish in a cauldron, and even just boil water in a kettle.

The vertical square tandoor is also quite versatile, but its design is less perfect, because the interior of the furnace will warm up worse in the corners. But you can bake bread in such a hearth, although you will have to place the cakes closer to the middle of each side. In all other cases simple design quite justifies itself, allowing you to bake meat in the same way or cook something in a kitchen utensil installed on top of the hole.

The horizontal tandoor is traditionally molded from clay, which makes it possible to make an arched vault without much effort. But also brick tandoor With front loading it is quite possible to do it yourself. When cooking in a container, you will need to place it inside the firebox. This gives the horizontal hearth a distant resemblance to a Russian stove. Cakes or samsa in Central Asia in this case are still baked, attaching them to the walls of the firebox.

Preparatory stage

Before you make a brick tandoor, you need to perform a number of preliminary work. They depend on the design of the hearth, but in general they boil down to the preparation of the base and the selection of materials. An important point in the manufacture of mini ovens cylindrical shape is the manufacture of the template. It is needed in order for the rounded arch to turn out to be even.

Brick for the tandoor can be taken as usual: red full-bodied or even facing. But the best choice there will be a refractory fireclay stone, which is designed for exposure to high temperatures. The heating and cooling time for all brands of brick is approximately the same.

In addition to building stone, a number of additional materials will be required:

cement, sand and gravel - for the foundation of the ground variation;
masonry mortar for stoves and fireplaces (dry mix);
a pipe with a diameter of 10 cm (asbestos cement, sandwich, tin) - for some models of tandoors;
grate;
clay;
reinforcing mesh, wire;
cutting boards and plywood;
grinder and disk for ceramics;
measuring tools.

If you add a building decorative elements, then the tandoor can even decorate the site. In this case, it is best to sketch the building in color, and then make drawings according to the desired dimensions of the hearth.

The place for the mini-oven must be chosen so that the building is flooded with water as little as possible during the spring snowmelt. If necessary, you can build a raised platform for its installation. For a ground model, you will have to fill in the foundation, and for an in-depth model, you will have to dig a hole.

How to make a ground tandoor

For a furnace of this design, a foundation is required. Even a small tandoor will weigh quite a lot, so during the period of thawing and freezing of the soil, it can lead and the masonry will simply crumble. But since the building is still not very large, you can get by with a slab foundation, the dimensions of which should exceed the diameter of the furnace by at least 20 cm around the entire perimeter.

Under the foundation, you need to dig a pit up to 50 cm deep. A layer of sand or ASG should be laid at the bottom of the pit, leveled and tamped. The thickness of the pillow is 10-15 cm. After that, a solution is kneaded from 1 part of M400-M500 cement, 3 parts of fine sand and 4 parts of crushed stone, adding water until a plastic mass is obtained.

Concrete must be poured into the pit, filling it to the level of the soil. Then install the formwork from the boards along the contour of the pit and raise the level of concrete by another 5 cm. If you want to protect the homemade brick tandoor from melt water, the site can be made higher. After preparing the base, work will have to be interrupted for 7-10 days until the concrete gains strength.

Cylindrical tandoor masonry

Before you build a brick tandoor, you need to make a template. The construction of boards and plywood is traditionally used:

Pick up a pole with a length not less than the height of the future tandoor (about 1.2 m).
Attach slats to it in increments of 30 cm (along the height of the pole). The length of the bottom and the one following it is 30 cm. Then you need to make smaller boards, forming a bend: the length of 3 supports is 25 cm, and 4 bars are 20 cm.
Attach a strip of plywood to the free ends of the laths, bending it in accordance with the profile formed by the shortening parts. The length of the rails can be chosen arbitrarily, depending on the size of the hearth, and be half its diameter at the base and at the top. A convenient height of the oven is about 1 m.

The laying of a vertical configuration tandoor begins with the formation of its bottom. To do this, several fireclay bricks must be laid on the foundation without mortar. Draw a circle on them, with a diameter equal to the future building. Taking out 1 piece, cut off the excess parts of the stone with a grinder with a ceramic disk. After sawing, the bricks must be put in place. The result is a round base. In order not to confuse the parts during masonry, you should number them.

Remove the base parts from the foundation, prepare the solution. You will need a refractory mixture for laying stoves and fireplaces. In the dry composition, add water according to the instructions on the package, kneading a viscous clay dough. Apply the mortar to the foundation, lay out the numbered bricks, pressing and lightly rubbing them to the base.

The construction of walls can be done in different ways:

install the brick vertically, with a long narrow edge outward;
perform the usual masonry in 1 brick around the circumference;
place the stones with the poke side out (for this method, halves of bricks are usually taken).

If the masonry elements are installed vertically, you need to slightly trim the ends (butt sides) of each brick. So they will easily form a vault.

Set the template on the bottom of the future tandoor. At the same time, the pole should be located in the center of the brick circle, and the plywood strip should be 12.5 cm from its edge. A bed of mortar should be applied to the free space.

After that, the laying is carried out, pressing the inner edge of each brick to the template plywood. Turning the pole, lay out 1 row in a circle. At this level, you need to leave a small hole for blowing. Therefore, 1-2 bricks in the masonry are not installed.

The next level is raised according to the same principle, pressing the edge of the stone against the template. The masonry parts must be shifted relative to the lower ones in order to get the dressing of the seams. Block the blower hole, completely closing the ring of fireclay bricks. Tie and tighten the row with thin steel wire or reinforcing mesh.

Continue to raise the walls of the tandoor, orienting the narrowing of each circle along the pattern. When laying bricks vertically or with a poke, it is imperative to ensure that the inner faces of each of them are in contact with the neighboring ones. As a result, small gaps are formed between the outer sides. You can fill the space between the parts with the same masonry mixture during work.

After the construction of the brick tandoor is completed, the template must be removed through the upper hole. Align the internal surfaces by applying a clay mortar or a refractory mixture to them. Cover with clay and the outer surface, finishing it to taste: facing with stone or tiles, decorative mosaics or otherwise.

The side of the hole on top must be carefully smeared with clay dough, giving it a roundness. Very often, at this moment, supports for suspensions are formed. To do this, you just need to make 4 cross-shaped recesses in the upper edge of the tandoor. It will be possible to put sticks in them, on which skewers with meat, a grill for roasting vegetables, etc. will be hung.

Square tandoor

A very simple hearth model can be made by hand even without a template. To build a square brick tandoor oven, a rough order of 2.5x2.5 masonry stones can be used. If desired, you can choose other sizes, the principle of construction will not change. The coarse pattern has a hole for the furnace door. Since the vertical tandoor does not have this detail, you need to lay out bricks where the door opening is indicated.

The slab under the foundation must be poured in the appropriate form, and after the concrete has hardened, lay bricks on it, forming the base in the form of a square. Elements of the next level should overlap the joints of the lower bricks. In the middle you need to leave a small hole for blowing, bringing it to one of the sides of the square. Raise 1 more row, install the grate.

At the next level, overlap the blower channel by laying out a solid hearth with a hole above the grate. For the walls of the furnace, several rows should be laid around the perimeter of the square, carefully aligning the verticals of the sides and the horizontality of the upper edge. At a convenient height, you need to start narrowing the dome.

To get a kind of furnace roof, you need to slightly move each element of the masonry inward. In this case, you will have to cut the bricks so that they fit on the ever-shortening sides of the square. When the top hole reaches a size of 20x20 cm, you need to slightly raise the side. Clean the internal surfaces from the influx of the solution; if desired, the stove can be plastered from the outside.

How to make a tandoor in the ground?

On a dry and elevated area, you can make a furnace, wholly or partially immersed in the ground. Such a building can become the center of a recreation area, replacing the Scandinavian hearth. Before you make a tandoor with your own hands out of brick, for such a design it is necessary to find a sufficiently long asbestos-cement pipe for making a blowing channel.

Given that the height of the tandoor is about 1.2 m, you need to be prepared to dig a pit of the specified depth. With partial deepening, the pit may be smaller. Its width is chosen arbitrarily. At the bottom you need to lay a layer of ASG, tamp it down and pave the pit with bricks.

1 row of masonry is laid out on this impromptu foundation. The shape of the stove can be round or square, and the building stone can be laid both with a spoon and vertically. After 1 tier is formed, a pipe for blowing should be installed. To do this, a trench must be dug with a slope that will allow the other end of the pipe to be brought to the surface of the soil. To fill the gap between the wall of the pit and the masonry, you can use excavated soil or ordinary clay, sand, crushed stone.

At the next levels, the furnace walls simply need to be raised to the desired height above the ground. If the building will have to perform decorative functions, finish the edge according to your own taste. In order for the tandoor not to cool too quickly, you need to choose a lid that is suitable in diameter for the upper hole.

What is a horizontal tandoor?

The Central Asian oven is also very interesting, in which there is no upper hole. Its pharynx is located on the side, which makes such a design related to the Russian or Pompeian oven. The manufacture of a tandoor of this design is traditionally made from clay mixed with straw or sheep's wool. Near such a hearth it is convenient to bask in the winter cold, it is often installed under the roof, indoors. But the construction of a brick tandoor is also possible in this case.

To create it, you need a circle, or a template made of plywood and boards. It will help you quickly build a tandoor with your own hands, ensure ease of laying the vault and give support to the bricks until the mortar sets. A template is made in the form of 2 connected arches, the width of which is equal to their height. You can draw a circle of the desired size, draw a horizontal diameter and lower 2 straight lines from the points of intersection of it with the circle. Transfer the resulting figure to plywood and cut out 2 identical parts.

Connect them with bars along the top edge. The length of the rails is equal to the desired oven depth. Sheathe the upper edge with thin plywood, bending the sheet along the contour of the arch and attaching it to the bars.

Prepare the base of the oven. Traditionally, it is built in the form of a table about 1 m high. For the base, you can use cinder block, brick, natural stone. You can weld the construction of a steel corner and put a metal worktop on top.

A layer of bricks on a clay mortar is laid on the finished base, forming a furnace with a channel for blowing. On the next row, you need to block the channel, leaving a hole in the center.

After that, install the circle on bars 3-5 cm thick and align it horizontally and vertically. For masonry, it is best to use wedge-shaped bricks, specially designed for the manufacture of vaults and arches. In their absence, cut off a part of an ordinary masonry stone, giving it the desired shape.

Lay out the uncut stone with a spoon in 1 row to the left and right of the template, close to its plywood vault. When shifting the bricks for dressing the seams, evenly raise both sides to the beginning of the arch. After that, use only cut or wedge-shaped stones, gradually closing the arch in the middle. Leave a small hole for the chimney. Dry the masonry for 4-5 days.

Carefully knock out the bars from under the wheel. At the same time, it will drop a little, which will allow you to freely remove the template from the firebox. Install grate.

Brick the open back of the arch. On the facade, you can make a damper or decorative doors. Press in the chimney pipe and bring it outside if the stove is located indoors. For an outdoor stove, a chimney is optional.

Preparing the tandoor for operation

But the work on the made tandoor is not over: the hearth laid out with your own hands must first be burned. They do this only after the clay has dried, that is, a few days after the construction of the building itself is completed.

Make a fire out of paper and small chips. Heat the oven until the outer surface is heated to +350°C (warm to the touch). Extinguish the fire and let the stones cool completely. Next time bring the oven temperature up to about +700°C (hot). It can cool for several hours, you can leave it overnight.

The last heating should heat up the tandoor to the operating temperature (+1500°C or more). After that, it is completely ready for use.

To bake bread and samsa, you need to heat the oven well and let the firewood burn down to coals. Dough products are glued directly to the walls. The cauldron can be installed on round hole from above, and skewers with meat are hung on sticks in a vertical position. You do not need to turn them, as they heat up evenly from all sides.

Staying in the country is a unity with nature. I want to cook food on the fire, sit by the fire, listening to the twilight rustles. For cooking on fire, a barbecue or barbecue is most often used, and we suggest you make a tandoor with your own hands. What it is? This is an oriental oven-brazier, which allows you to cook a lot of delicious dishes that are simply impossible to cook otherwise. Samsa, pita bread, oriental meat - all this can be done in the tandoor. Moreover, the meat turns out to be very tasty, because it is suspended in a horizontal position, as a result, the fat does not drip onto the coals, but flows down the pieces of meat, making it juicy and soft.

Barbecue in the tandoor is much tastier because of the vertically arranged skewer. On the grill, the meat needs to be poured with marinade or sprinkled with water, but here it turns out tender and juicy

It is very interesting, in the opinion of a European, tortillas and samsa are prepared in the tandoor - they are attached directly to the walls of the oven and baked in this way.

Oriental cakes and samsa are baked in the tandoor, stuck to the walls of the oven. This bread has a special taste. Having made a tandoor, you can bake samsa, pita bread and delicious cakes

The traditional shape of such a furnace is round. It can be located both above ground and underground. Today, many summer residents build a brick tandoor, it is not so difficult to make it, but oriental cuisine will bring a lot of pleasure to both family members and guests.

In the East, the tandoor can also be located in the house, it is installed in the center of the room to warm the air in the room during the cold season.

A small tandoor can be made on a platform with wheels, you can transport it to any place in the garden.

You can also buy a tandoor if funds allow. Here is a ready-made tandoor with a platform on wheels that can be installed anywhere in the garden or in the house

If the stove is stationary, it is better to place it on rocky or sandy soil, away from buildings and green spaces. The ground under the tandoor must be dry.

How to make a tandoor? Stone blocks, ceramic clay bricks, or white refractory bricks can be used for construction. The base is laid out first. The brick tandoor is quite heavy, so the base must be strong. The base of the furnace is like a foundation in which an opening is made where fuel is laid.

You can build a tandoor directly on the ground, in this case you need to dig a hole in the shape of a circle under the base, with a diameter of 120-130 cm. We fill the bottom with sand (a layer of 15-20 cm), and we begin to lay out a brick well.

The base for the tandoor - a sand cushion is made at the bottom of the base, the area around is also covered with sand. At the bottom it is convenient to place the grate under the coals

As a mortar for masonry, you can use a ready-made oven mixture. It consists of a plasticizer, red clay and quartz sand. The masonry can be both horizontal and vertical, in the first case the stove will keep heat longer, the second is more economical - much less bricks will be needed.

Tandoor, lined with vertical masonry with a pipe for venting gases. Material for the manufacture of such a furnace consumes less

Brick tandoor, lined with horizontal masonry - the thickness of the wall is greater, so it keeps the heat inside longer. In any tandoor, there should be a hole for flue gases from below

To visually see the dimensions of the future furnace, you can first make an order - masonry without mortar. We work with a brick with a grinder with a cutting diamond wheel for ceramics.

Ordering is done for a visual representation of how your tandoor will look like. After such a calculation, you can start working with the solution. Tandoor can be built on the ground or on a brick base

It is not easy to make round masonry, a full-size drawing made with a protractor and a compass will help you, and the ability to handle a grinder is also important.

The diagram clearly demonstrates the device of a brick tandoor. Features of the manufacture of the furnace may differ, but the basic principle of construction is always the same - a base with a hole for fuel and a body that is rounded up

A pattern of bricks is the basis for forming a circle. Do not spare the mortar when laying, and use a level to check the horizontal position.

Oriental craftsmen used a similar pattern to make the tandoor. Laying bricks according to the pattern, the oven will gradually acquire a rounded shape tapering upwards

The tandoor is narrowed up - this is done so that the heat is kept inside. In order to achieve this effect, the bottom layer of the brick must be cut off; when laying, the shape will resemble a vault. After the masonry is ready, the interior of the furnace should be cleaned of traces of mortar. We use dry clay to fill the seams from the outside. The inner surface is also coated with clay, which is mixed with finely chopped grass.

When the kiln dries, it is first heated with paper, and then the firing temperature is increased. This is the easiest way to make a tandoor, and if you want to ennoble it, you can coat the structure with clay. In the east, stoves are decorated with mosaic tiles, sandstone, and ceramics.

The video demonstrates how to make a brick tandoor using a template:

Option # 2 - tandoor from a wooden barrel

Of course, a brick tandoor is the most durable and practical, but if you wish, you can use other methods, which we will now discuss. Here you need the skill of working with clay.

You need to find a small barrel with ill-fitting hoops. The barrel is impregnated from the inside with refined sunflower oil, for impregnation we leave it overnight.

Then we prepare a solution - sheep wool for reinforcement (length up to 15 cm), fireclay clay, fireclay sand. The ratio, respectively, is 0.05 - 1 - 2. We make a thick solution and fashion the furnace body on the inner surface of the barrel (thickness - 20-30 cm). The solution is smoothed and dried for a week using incandescent lamps. Then the hoops can be removed, and the barrel disassembled. After that, the product is subjected to secondary firing.

Option #3 - Brazier using a plastic barrel

You will need plastic barrel classical form. We fill it with water, after filling the barrel slightly increases in size, its outer surface is coated with fireclay solution, it is compacted, smoothed until the furnace contour is formed. The product is also dried for a week, and then the water must be drained. The barrel will become smaller and can be removed from the new tandoor.

A cauldron can also be placed on top of the stove for cooking pilaf and other dishes, but for this you need to adjust the crown to the volume of the cauldron, the crown is coated with clay.

Building the oven is the highlight, but you will also need to make the metal skewers. For example - these are three brackets with a metal hoop in the center. The easiest option is to use a strong rod, laying it along the crown, and attach skewers to it

If you have the skills of pottery, the tandoor can also be made a decoration on the site. For example, create such a “house” for cooking delicious oriental dishes

We examined several simple ways to make a tandoor in the country. These are the simplest answers to the question of how you can make a tandoor with your own hands. More complex options offer the manufacture of a structure resembling a Russian stove, but this is a bulky structure and it is quite troublesome and difficult to build it, and a simple tandoor is quite suitable for giving and the dishes in it are very tasty, try it and you will see for yourself.

For most city dwellers, being in the countryside is associated with unity with nature, when there is an irresistible desire to sit by the fire in the open air and cook food on the fire, inhaling the exciting aromas. In most cases, residents country houses they prefer to use a brazier or barbecue for cooking, which is widely used by residents of the middle lane. The oriental tandoor, less common among the European population, is in no way inferior to the listed devices and, on the contrary, allows you to cook a lot of delicious dishes, the cooking technology of which involves the use of only an oriental brazier. The unique taste of homemade samsa, pita bread and oriental meat is a weighty argument in favor of building a tandoor in the country with your own hands.

The principle of operation and design features of the tandoor

Before considering the construction of a tandoor oven, we advise you to familiarize yourself with the principle of operation and the main features of the traditional design, the performance of which has been tested for centuries:

Initially, the tandoor was a clay cauldron, located upside down and equipped with a hole in the upper part;
There is also an additional hole at the bottom for blowing;
Outside, a kind of clay cauldron is lined with bricks, filling the space between the tandoor and the brickwork with sand, clay or salt;
These materials have low thermal conductivity, as a result of which the clay oven becomes an ideal accumulator of heat, which it absorbs from fire, and then slowly releases it into the structure where food is cooked;
In this regard, a uniformly high temperature is created inside the oven, which makes it possible to bake and fry delicacies in conditions of complete absence of coals.

Features of modern construction: design and materials

At present, few people observe the traditional features of the building, greatly simplifying the manufacture of the structure.

Despite this, the tandoor, built in modern conditions, does not interfere with enjoying home-made oriental delicacies. The most common form of modern tandoors is considered to be a “well” or a jug, narrowed in the upper part, which prevents the outflow of heat and contributes to the uniform heating of the furnace.

Since the brick is used as the basis of the building, according to experts, it appearance does not play a special role, and in this regard, they offer to choose any red heat-resistant brick for making a tandoor, even those that have already been in use.

And to facilitate the work, to prepare the solution, you can use the factory oven mixture based on red clay. The solution prepared using this mixture is resistant to high temperatures, dries quickly and, due to its high plasticity, does not form cracks.

Do-it-yourself tandoor: preparatory work

Before you build a brick tandoor, you need to decide on the territory on which the structure will be located. According to safety regulations, it should be located at a distance of at least 3 meters from trees and outbuildings. It is desirable that the groundwater level is as low as possible and the soil is dry.

The selected site, the length and width of which often do not exceed 1.2-1.5 m, is carefully leveled and covered with a layer of sand equal to at least 20 cm. asbestos cement pipe. Those who are afraid of the harmful effects of asbestos can replace the asbestos-cement pipe with a metal one.

Sequence of work: foundation and walls of the structure

The next stage of construction involves laying out a site consisting of three rows of white silicate bricks. In the process of arranging it, there is no need to use a concrete solution, since in any case it will crack under the influence of excessively high temperatures.

In the future, you need to do the arrangement of the walls.

To install them, you will need a red heat-resistant brick placed on the end, with which you will get a circle of the required diameter. In this case, it is 40 cm, and consists of 19 bricks.

For greater accuracy, you can use a round template. In total, the design of the tandoor, the photo of which is presented below, involves the installation of three rows of bricks installed in a similar way, which took a total of 57 bricks.

To increase the strength of the structure, the rows are aligned and then tied with wire. As a result, the height of the brick walls of the tandoor, as the video confirms, is 75 cm.

Structural strengthening: reinforcing mortar, metal mesh and other techniques

Next, you need to start preparing a solution based on fireclay clay, which will be required to cover the seams between the bricks. carry it out manually. So that the brick does not absorb moisture from the clay longer, it is moistened before smearing the cracks.

After the first layer has dried, a second layer is applied, called reinforcing.

For its preparation, in addition to clay, straw is added. Thus, with a break of 2-3 days, necessary for the clay to dry, two layers are applied. It is important not to forget to cover the structure with polyethylene at night, which will protect it from moisture in case of rain.

To give even greater strength, the structure is reinforced with reinforcing metal mesh and again coated with a layer of clay.

Answering the question: “How to make a tandoor with your own hands?” let us clarify that the next step involves welding, which is carried out for the manufacture of a metal ring. It is installed in the upper part of the structure and the structure is again reinforced with a reinforcing mesh, which reaches the metal ring from above.

Having carried out the above activities, they coat the almost finished tandoor cement mortar. To prepare it, you will need sand, cement and granite screenings, the composition of which allows you to prepare a "light" concrete solution.

Experienced specialists involved in the construction of a tandoor with their own hands are advised to add a teaspoon to it when mixing the solution. detergent, explaining this by the fact that the solution in this case does not shrink. To mix the solution, it is best to use a drill with a nozzle. After coating the tandoor with concrete mortar, leave it to dry completely for about 7 days.

To design long time kept warm, care must be taken to make a wooden cover.

In addition, for these purposes, the tandoor is often additionally covered with a quilted blanket. Also, the design of the eastern stove implies the presence of a metal stand, on which skewers are subsequently hung.

Tandoor is a vertical brazier used in Asian countries. Fragrant cakes, barbecue, real pilaf and much more can be cooked in this wonderful oven in a few hours. How to make a tandoor with your own hands from brick? The portal site will help you figure it out and provide several options for building.

Brick tandoor scheme

There must be insulation between the outer and inner contours. The outer contour may have a different shape. In this case, concrete blocks were used as the foundation.

Be sure to arrange a blower. This part facilitates maintenance and increases safety.

Step-by-step instruction

How to build a large brick tandoor? Step-by-step instruction:

We draw the project. We dig a pit with a diameter of 1 m to a depth of 200-300 mm.
Doing sand base under the foundation. Pour sand in a layer of 100 mm and carefully compact.
We fall asleep with sand
We reinforce the foundation. We use a wire mesh VR-5 with a cell of 150x150 mm. Sold in hardware stores, in rolls of 6 meters.
The mesh must be completely filled with concrete. The minimum thickness of the protective layer is 40 mm. To do this, the grid is laid on bricks.
We fill the resulting structure with concrete. For the construction, concrete grade B12.5 is suitable for us. The recipe is beyond the scope of this article. Concrete must be carefully compacted. Horizontal control is carried out using a level.
Checking the level
To gain strength, we withstand the base for seven days. In summer, be sure to moisten with water.
We insulate the bottom with fireclay bricks.
We mark the inner contour of the future furnace at the bottom. In a clockwise direction, we begin to arrange the bricks along the contour. Lay out in 2 rows of ½ bricks. To make the design look neat, we will make a wooden template. In the bottom row we leave an opening for the blower.
We start laying

We leave a place for a blower and an ash pan

We put the grate

Don't forget to check the level.
We are waiting for the structure to dry (the site recommends waiting at least a day).
Outside, we insulate the inner contour in 2 layers. As a heater, basalt wool is suitable.
We mark and lay out the outer contour. The top row is carefully coated with clay. Verticality is controlled using a template. We adjust the brick to the template, cutting off the end with a grinder.
Laying out the outer contour

End of work
You can weld a fixture for attaching skewers.
