Glaze Color Property

Glaze color is a combination of chemistry between the colorant and host, firing process and the amount and nature of the colorant. It is possible to achieve very similar colors using very different systems, and very different colors by making very small changes in a system. Often the trade offs associated with different approaches to making a similar color can be quite complex.

Glossary	Colorant In ceramics and pottery, colorants are added to glazes as metal oxides, metal-oxide-containing raw materials or as manufactured stains.
Glossary	Transparent Glazes Every glossy ceramic glaze is actually a base transparent with added opacifiers and colorants. So understand how to make a good transparent, then build other glazes on it.
