Alumina Hydrate (Dry)


Hydrated alumina is a fine granular white powder that is typically added to glazes as a source of alumina.Melting point 3000°C

The hydrated version of alumina remains in suspension better in glaze slurries, and has better adhesive qualities thanCalcined Alumina Oxide. Small additions of alumina hydrate to a glaze can also enhance the color of Cr-Al pinks. Larger additions can impart dullness in the glaze.
