Q Is there any way to minimize the spalling and cracking of firebrick that results from firing conditions?

A There are several causes of brick cracking or spalling in a kiln lining: kiln construction, fast firing, chemical attack and poor choice of refractory.

Kiln Construction. Some spalling of firebrick is caused by the construction of the kiln. Often called "pinch spalling," this results from insufficient expansion of the joint dimension. If there is not e...
