Alumina Hydrate/ Alumina Hydroxide is a source of alumina in glazes. It is more correctly referred to as Aluminum Hydroxide, Al2O3.3H2O, but in studios and labs you will frequently hear it called alumina hydrate. It is a fine granular white powder, and because it is hydrated, it remains in suspension well when used in glazes. Small amounts decrease fluidity of glazes when they melt. In certain pink glazes, a small amount of alumina hydrate can enhance the color outcome.

Alumina Hydrate, however, is rarely used in large amounts in clay bodies or in glazes (as most of the necessary alumina comes from clay and feldspar). You will most frequently encounter this material as a primary component used in kiln wash and wadding due to its high melthing point.

You can find calcined Alumina here.
