Tiles for the stove: a) central flat tile, b) flat corner tile, c) central coronary tile, d) corner crown tile, -e) box base, f) jam.

The tiles are used for the outer casing of the stove. They are made of various types of clay with an admixture of refractory clay and powdered marl. The tiles are also made of refractory clay only with the addition of ground fireclay.

The first is called refractory tiles, and the other with chamotte tiles.
The tiles can be manufactured by hand or by machine. After forming and drying, the tiles are fired in an oven at a temperature 900 do 1000°C, depending on the type of raw material used for production. After firing, the tiles are glazed, and then fired again to obtain glaze by fusing the glaze.

Refractory tiles can be distinguished from chamotte tiles by the color of the shell. The body of the fireproof tile, fired from marl clay, is red, while the shell of the fireclay tile is yellowish or white in color.

Depending on the color of the glaze, we distinguish between white and colored tiles. Unglazed tiles are also produced.

On the inside, the tiles have collars, commonly known as rumps.

Because a well-made furnace requires, so that the joints between the tiles are as thin as possible, the dimensions of the tiles used in the construction of the stove must be very accurate. In accordance with the applicable standard for tiles (PN-58/B-12041) deviations from the dimensions of the length, the width and height of the tile must not exceed 1,5 Mm. However, because it is difficult to achieve the required accuracy in production, the dimensions of the tiles in the plan are usually larger, and the required accuracy is achieved by cutting and polishing the edges of the tile on the construction site.

Until recently, two types of tiles were produced: regular and so-called. square. Square tiles were widespread in Poland before the war and produced them small, poorly equipped tiled houses, unable to make larger tiles. Currently, they can only be found in old furnaces. They were replaced by ordinary tiles from the construction industry, because the appearance of a stove made of square tiles is worse than that of ordinary tiles, and the numerous welds promote dust accumulation and the formation of leaks in the furnace.
