Abstract: A process for producing a zirconia bearing opacifier is disclosed. The process comprises the steps of: (i) heat treatment of a zirconia bearing material comprising heating the zirconia bearing material in the presenoe of an additive to form a heat modified product having one or more phases which, when incorporated in a glaze and the glaze is fired, exhibit opacifying characteristics; and (ii) cooling the heat modified product to produce a product which can be used for imparting opacity.
