RefractoryWikipedia
A refractory material or refractory is a material that is resistant to decomposition by heat pressure or chemical attack and retains strength and form at high temperatures. Refractories are polycrystalline polyphase inorganic nonmetallic porous and heterogeneous. They are typically composed of oxides or non oxides like carbides nitrides etc. of the following materials silicon

Features Classifications and Applications of Fused Cast
Fused cast refractories are the preferred refractories in contact with glass melts due to the chemical stability impermeability and resistance to corrosion and erosion at the working temperatures in the glass melting furnaces. Therefore used cast refractories are widely used in the glass industry as a lining for glass melting furnaces.

Iron- and manganese oxides culprits of refractory erosion
Jul 01 1996 · Erosion of refractories occurs when there is a localized or uniform reduction of the refractory thickness due to chemical or mechanical means. Chemical erosion between the refractory and the ferrous melt is commonly referred to as "corrosion." This type of erosion is often the direct result of iron- and manganese oxide attack on the refractories.
