Using Oxides In Ceramics

Bisqueware absorbs the color easily so the two materials work well together.

Using oxides in ceramics.

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. Cover with transparent or translucent glaze. Pick up some new ideas for how to decorate bisque pottery with red iron oxide by watching this video ceramic design tutorial. This is a video tutorial of decorating bisque with red iron oxide.

Some potters will use oxides and stains suspended only in water. It discusses the importance of wiping back how to avoid uneven coverage and many other useful hints. Use other masking techniques such as torn wet newspaper and paint an oxide wash. However some plain oxides like cobalt and chromium oxide and some ceramic stains are quite refractory.

For example when pure chrome oxide is used as a colorant to obtain green it may fume or volatilize in the kiln leading to absorption into the kiln bricks and shelves. Or do the same thing with oxide over unfired glaze. A demonstration of how to use an oxide wash on pottery. Their application areas depend on their melting points and maximum use temperatures.

In short oxides and stains can be used in very similar ways. 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. Ceramic stains make it possible to create glazes that fire to just about any color of the rainbow.

This can cause problems with adhesion. When dry scratch with a sharp tool through the oxide to show the clay underneath. They are both quite versatile ways of coloring ceramics.
