The action of polishing or burnishing.

The process of applying a glaze to a piece of pottery. A glaze is a vitreous layer that is formed on the surface of a ceramic when a mineral is applied to the surface of a bisque fired ceramic ware that is then fired again. The application of heat causes the mineral to fuse to the surface of the ceramic. Glazes can be applied by dusting the dry mineral over its surface, liquid glazes that are a suspension of minerals and metal oxides can be applied by dipping, painting, spraying or pouring on to the ceramic. Glazes are applied to strengthen, decorate, colour or waterproof ceramic surfaces.
