The mostly applied type of refractory in the glass industry, in direct contact with the glass melt, is fused cast AZS. Due to the interaction of the glass melt with fused cast AZS, glass defects like stones, knots and bubbles can be generated. Fused cast AZS block exudation is thought as the leading cause of knot and cord defects.

When the moisture freezes, it expands and over a period of time it can cause cracking and flaking. Sulphur from flue and exhaust gases combines with moisture in the atmosphere to form sulphurous acid which falls as acid rain. This attacks many types of ceramic building material and in particular, natural stone. The refractory ceramics used to
