A large chart showing each stain. The rows are grouped according to type and each row has tags that references temperature capability and chemistry requirement for the host glaze. There are also columns for each element and the rows have check marks for each contained.

Blue and orange stains in Zero4 porcelain fired at cone 06
Mason 6315 zirconium vanadium blue 1-10% and Mason 6028 Orange 1-10%. In both cases, 6% appears to achieve maximum color (colors will be even brighter when fired to the full cone 04). Both of these are listed as candidates for staining bodies on the reference guide at masoncolor.com. Fritware bodies like this have much more glass development during firing than porcelains and thus amplify stain colors better. It is typical to only use body stains for this type of experiment, but because the firing temperature is so low and firings can be done quickly it is likely that more stains will work that in typical cone 6 or 10 porcelains. This is potentially a good process for jewelry making. Photo courtesy of Karen Ho Fatt Lee.
A cone 10R blood red - without copper but with risk
This is G1947U clear glaze with 8% Mason 6021 encapsulated red stain added. The body is P700, a Grolleg kaolin porcelain. The one on the right, having significantly reduced clouding within, has one tiny addition: 2% Zircopax. It is acting as a micro-bubble fining agent, producing a brighter color and smoother surface. But there is a possible problem: These stains are not recommended for use above 2300F. Even though the color is very good, cone 10 is just on the edge of the limit temperature, so suitability for food surfaces would require careful testing for leaching cadmium.

Encapsulated Stain
This is a type of stain manufacture that enables the use of metal oxides (like cadmium) under temperature conditions in which they would normally fail. |
