| Fireclay is a type of clay which is used in the production of heat resistant clay items, such as the crucibles used in metals manufacturing. This type of clay is commonly mined from areas around coal mines, although other natural deposits are also available as potential sources, with many nations having deposits of clays suitable for use in high temperature applications. Fire clay can also be refined and treated to make it suitable for specialty applications.
This type of clay has a very high fusion and melting point. Once it is worked and fired, it will hold up to extremely high temperatures such as those found in kilns, furnaces, and retorts, in addition to the high temperatures of some production lines. Fire clay can also be used to create fire resistant chimney and flue liners, and fire resistant pads for safety, as seen when a hearth in front of a fireplace is made with fireclay to reduce the risk of fire. In many settings where there are concerns about fire, fire clay can be used. |
