Alumina

Powdered alumina (Al₂O₃) is an extremely refractory material. It does not even fuse at cone 10, remaining a soft powder.

Alumina powder is not normally sold at ceramic suppliers, but they typically carry Alumina Hydrate (or Alumina Hydroxide). Calcining the alumina by putting it in a bisque firing will produce alumina.
