Alumina Hydrate
Al2O3 Calcined and Al2O3.3H2O or Al2(OH)6 Hydrated aluminas are fine granular white powders that have good flow properties increasing glaze viscosity and firing range and also resistance to crystallisation. This material has a very high melting temperature. It is important that the powder is very fine.Visit the Castree Kilns website for more information on Alumina Hydrate
