Staining Ceramic Clay Pigments Ceramics, often referred to as ceramic body stains, have vastly opened up the color possibilities for potters. And as we all know, adding color to your ceramic art can be a tricky proposition. Unlike working with paints, the raw opaque glaze you put on your prize pot or sculpture often looks completely different from the fired result. So it helps to have a good understanding of all of the options out there for ceramic artists.
A ceramic pigment powder is usually a metal transition complex oxide obtained by a calcination process which shows three main characteristics: (a) thermal stability, maintaining its identity when temperature increases; (b) chemical stability, maintaining its identity when fired with glazes or ceramic matrices; and (c) high tinting strength when dispersed and fired with glazes or ceramic matrices.
Prepared pottery pigments, commonly referred to as ceramic stains, expand the potter’s palette with infinite possibilities. Clay pigment provides a wide range of color possibilities in clay bodies, inglazes, underglazes, and onglazes.
Depending on the use, pigments of potter may be used straight and just mixed with water, but they are more commonly added as colorants in clay bodies and glazes. Some pigments are strong: Bumblebee yellow color code. Another, like Candy Red, requires a higher percentage of mixing. Some pigments are specifically formulated for clay bodies while some are not suitable at all. Unlike ceramic lustres, when used in a clay, pottery pigments are usually used in engobes and slips as a coating for clay rather than pigmenting the entire body. The exception to this would be using stains to tint porcelain for neriage work like Welte glazes. Using opaque ceramic glaze is not recommended over pigments, volcanic glaze too. If you are looking for a glaze effect you can use any luster for ceramics.
Ceramic color pigments are used for the decorating of utilities and ornamental ware of porcelain and of the glazed ceramic products. This colours are resistant partially against chemical influences. On the dab and desiccation, the colours are burnt at the appropriate temperature at perfect kiln ventilation. On the attainment of maximum firing temperature, the temperature is kept for the duration of c. 10 minutes.
The black iron oxide ceramics is generally this synthetic form (the natural equivalent mineral magnetite contains 5-15% impurities). Red iron oxide is the most common colorant in ceramics and has the highest amount of iron. It is available commercially as a soft and very fine powder made by grinding ore material or heat processing ferrous/ferric sulphate or ferric hydroxide.
