Using Oxides In Ceramics

Or do the same thing with oxide over unfired glaze.

Using oxides in ceramics.

Prepared stains prepared oxides modified oxides inorganic colorants coloring oxides how to use stains when introducing a ceramic stain into a glaze recipe it is best to mix powdered stain with hot water sieve through a 200 mesh screen then add to the wet raw glaze batch. Their application areas depend on their melting points and maximum use temperatures. Red iron oxide can be layered fired watered down and used in many ways to add a finish to a piece of bisque pottery. This is a video tutorial of decorating bisque with red iron oxide.

Some potters will use oxides and stains suspended only in water. When dry scratch with a sharp tool through the oxide to show the clay underneath.

Ceramic pigments solve some of the problems found in using just plain oxides. But one drawback is that the glaze surfaces colored with ceramic stains often lack the depth of those glazes that use ceramic oxides. In short oxides and stains can be used in very similar ways.
