Typical application
ZMP 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 ZMV for application in complex and large shapes.
