Typical application
ZMV is manufactured with zircon-mullite fused grains providing a high corrosion resistance to alkali vapours. Used in forehearth superstructure subject to high corrosion such as sodalime coloring zone or soda-lime extra white glass.
Refer to ZMP for application in standard brick format.
