In 1958, he himself made a brick and built a furnace out of it. How did you do it? Prepared clay and sand. Knocked down a shape for five bricks from 25 ... 30 mm boards (Fig. 3). Form with side walls, but without bottom. To determine the correct formulation of the clay mixture for bricks, he prepared five different versions of the mixture, in which the ratio of clay and sand varied widely. Then he laid the mixture in the mold compartment, having previously placed it on the board.
Of course, we number the mixtures and write their composition. Two days later, raise the form, leaving the bricks on the board. On the third day, put the bricks on the edge. After another two days, the bricks will dry out and you will understand which clay composition is the best. (The suitability of the clay mass for making bricks is determined as follows. Molded from clay is a “sausage” with a diameter of 4 cm and a length of 50 cm. A ring is made of “sausage”, laid on a board and pressed onto another board, flattening the “sausage” to a thickness of 2 cm If there are no cracks in the ring, everything is in order. - Editor’s Note.)
Now we dig a round hole and in it we barefoot knead the clay mass of the selected composition. We put the form on a long board, put a lot of shovel into the nests, tamper it well, align the top with the board, cutting off the excess. We move the form further along the board, and raise it, leaving the bricks on the board. Then we repeat everything again. It goes without saying that this work is carried out in dry weather. Having formed one or another number of bricks, we leave them to dry for two days, after which we turn on the edge. Two days later. We put the bricks under the canopy, where we put them in a “box”, putting the bricks on the edge. The total drying time depends on the weather and is usually 1 ... 3 weeks. (Try to make the bricks neat, because when laying the stove, the seams should be minimal, otherwise the bricks will get wet.) Ceiling butchering and the pipe are laid out from burnt bricks.
Having folded the oven, 3 ... 4 times carefully, without overheating, weep it, dry it, and then plaster it. It would be nice to add a little horse manure to the plaster solution.After grouting and drying, the oven is bleached with lime.
