Quick Summary

Fireclay, also known as refractory clay, is a type of clay capable of withstanding high temperatures. It is primarily used in the production of firebrick and crucibles. Firebricks are essential refractory materials used in high-temperature structures, particularly in metallurgical operations and glass manufacturing.123

Clay, in general, refers to soil particles less than 0.005 millimeters in diameter, or rock composed of these particles. Clays are formed through weathering and are crucial for plant growth, providing aeration and water retention. Beyond their role in soil, clays are vital in industries such as pottery, construction (bricks and adobe), paper manufacturing (kaolin), and as drilling muds.4
