What soil is put in the brazier?

There is clay in the brazier. Because it is mixed with clay with a certain viscosity, it is shaped with a wooden brazier and dried in a drying kiln, which becomes a clay brazier for heating in winter. The whole process includes casting and heat treatment, so clay is put in the brazier, which has the characteristics of burning resistance.

Clay is a kind of cohesive soil, which contains less sand and is difficult for water to pass through, so it has good plasticity. The stove is made of clay.

Structure of clay

Clay, also known as clay, is a very small plastic aluminosilicate. In addition to aluminum, clay also contains a small amount of magnesium, iron, sodium, potassium and calcium, which is an important mineral raw material.

Clay is generally formed by the weathering of aluminosilicate minerals on the earth's surface, but some diagenesis can also produce clay. The appearance of clay in these processes can be used as a sign of the progress of diagenesis.

Clay is an important mineral raw material. It consists of various hydrated silicates and a certain amount of alumina, alkali metal oxides and alkaline earth metal oxides, and contains impurities such as feldspar, mica, sulfate, sulfide and carbonate.

The particles of clay minerals are fine, often in the range of colloid size, crystalline or amorphous, most of them are flaky, and a few are tubular and rod-shaped.
