The firing of these bricks were placed across 15 pieces fields, and they have already posed designed for baking dishes – about 100-200 products of average size. By the same author: Charles Schwab. After as a potter has exhibited the dishes, he flooded oven, pushing in the mentioned grooves kindling thin dried Polenz. They are lighted cross slaughterhouse, crockery glowed in a few hours already had a kind of red-hot iron. Usually been heated oven for about four hours – five, and all this time potter regularly underlay the furnace new Polenz and each time turned a blind hole brick grooves, playing the role of ash. At this time in the studio became so hot and hard, to stand upright was completely unbearable.
Smoke and heat accumulated at the top, and the potter was forced to squat on the floor before the stove, and keep track of the furnace. In case of fire in the studio is always was stocked water. Fires usually occur on what ignited the drying on the stove "fired up", although it covered a sheet of iron. In contrast to the kiln furnace placed outdoors, usually on the steep river bank, slope of the ravine, hill about 100 yards from the buildings. Horn, consisted of a circular pit, somewhat tapering upward, a foot in 1,5-2 depth, diameter at the bottom of 2-2,5 yard. Yama bricks were laid in the hearth had holes. Under the hearth were heat pipelines coming from the furnace and fireplace itself was not a pit, and a few side and out his hole in the ground, cleared in the hillside below the hole furnace. The laying of dishes in the horn down to the potter He was putting the dishes and carefully so that it does not cover the holes in the hearth: This prevents the bowl from direct contact with flame; openings fenced shards of broken pottery.
Top of the dishes, too, were covered layer of broken crocks. Roasting in the furnace lasted hours 7-8, during which time the furnace underlay wood. After firing in the furnace and the furnace cooled dishes 12-14 hours. Removed her hands or a stick-lever if it was still hot. Excavated the dishes were placed directly on the cart and carefully shifted hay. Products in the furnace fired once. After firing, that they were not allowed water, their lard. Of mining was different: from 0.1 m3 to 500 m3. For pottery, porcelain built a double-decker ovens with heat recovery.
