What is fire clay?

Fire clay is a type of clay that is highly resistant to heat and is used in the production of high-temperature resistant ceramic products. It is typically found in deposits near coal seams and is formed from the decomposition of granite rocks.

Fire clay has a high melting point and low thermal conductivity, making it ideal for use in kiln linings, furnace linings, and firebricks. It is also used in the production of refractory materials, such as crucibles, insulating bricks, and ceramic tiles.

Fire clay is often blended with other materials, such as grog or silica sand, to improve its strength and workability. It can be shaped and molded into various forms before being fired in a kiln at high temperatures to create durable, heat-resistant products.

Overall, fire clay is a versatile material that plays a crucial role in the manufacturing of products that require high-temperature resistance, making it essential in industries such as ceramics, metallurgy, and construction.
