Zeolite Pigment

Description
Zeolite is a handmade natural pigment ground from zeolite, a family of porous aluminosilicate minerals. It produces a soft, green with a fine, matte texture. It has low hiding power and works best as a soft, natural tint and extender.

In use, Zeolite adds body, tooth and a matte surface to watercolor, gouache, tempera, distemper and encaustic, and it can be used to make subtle, stony green neutrals when mixed with earths. Its porous structure gives it good absorbency in grounds. It is lightfast and chemically stable.

History
Zeolites were first described in 1756 by the Swedish mineralogist Axel Fredrik Cronstedt, who named them from the Greek for "boiling stone" because they release steam when heated. Natural zeolites formed in volcanic ash deposits were used in Roman pozzolanic cements and building stone. As a painting material zeolite is new, giving artists a mineral white with a distinctly stone like character.
