Alumina Hydrate
Al(OH)3—alumina source, rarely used in clay bodies or glazes, because all needed alumina comes from clay and feldspar. Used primarily for shelf wash and wadding—better adhesion and suspension than aluminum oxide (Al2O3). Small additions increase viscosity of glaze melt. Alumina Hydrate Should not be used as matting agent in functional glazes—produces immature glaze.
Occasionally the preferred source of alumina in a glaze because it remains in suspension for a longer time and can be more reactive.
