Using Oxides In Ceramics

It discusses the importance of wiping back how to avoid uneven coverage and many other useful hints.

Using oxides in ceramics.

They are both quite versatile ways of coloring ceramics. Cover with transparent or translucent glaze. Red iron oxide can be layered fired watered down and used in many ways to add a finish to a piece of bisque pottery. 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.

A demonstration of how to use an oxide wash on pottery. This can cause problems with adhesion. Spatter wax on the surface and paint the oxide wash over that. Bisqueware absorbs the color easily so the two materials work well together.

The mostly known examples for oxide ceramic fibers are composed of oxides such as silica sio 2 mullite 3al 2 o 3 2sio 2 alumina al 2 o 3 and zirconia zro 2 having different characteristic properties. 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. However some plain oxides like cobalt and chromium oxide and some ceramic stains are quite refractory.

Or do the same thing with oxide over unfired glaze. Ceramic stains make it possible to create glazes that fire to just about any color of the rainbow. Their application areas depend on their melting points and maximum use temperatures. In short oxides and stains can be used in very similar ways.

This is a video tutorial of decorating bisque with red iron oxide. But one drawback is that the glaze surfaces colored with ceramic stains often lack the depth of those glazes that use ceramic oxides.
