Some tips for inclusion pigment:
This photo clearly shows what is meant by the phrase "inclusion pigment":
You can see the red cadmium-selenium-sulfide particles enclosed in colourless, transparent zirconium silicate crystal.
Cd-S-Se is thermally stable up to 900°C in normal atmospheres. Beyond that the pigment decomposes to form CdO, SO2, SO3, and SeO2, and loses its colour and pigment quality. As long as the Cd-S-Se particles are embedded in the ZrSiO4 crystal they are protected against oxidation and the chemical attack of the glaze frit or flux.
Instructions for application of Inclusion Pigments
1.Black dots: black dots phenomenon, i.e. the brownish-black spots appeared on the surface of ceramic wares calcined with medium and high temperatures, is a weakness in the application of inclusion stains. Experiments have proven that this phenomenon is related to the ceramic body, frits as well as the pigments used. This problem can be solved by “Compensative encapsulation” and adjustment of frits.
