Zircwash is a water-based paint that yields a low-to-medium-hardness coating that is 97% Zirconium Oxide [Unstabilized] and 3% Aluminum Oxide after heating to above 600°C (1112°F).   Easy-to-use coating that can be used to 2000°C (3632°F). Since the coating CONTAINS NO SILICA, Zircwash is far superior to Zircon (Zirconium Silicate) coatings for melting/casting operations.
