FUSED CAST AZS 33

The compact microstructure of Fused Cast AZS 33 enables it to have very good corrosion resistance to molten glass. It very rarely results in stoning and has very limited chances to cause blistering and other defects to glass, so AZS 33 is the most common product used in the glass furnace
