Epidote

Epidote

yellow-green earth

 

Product Information

This coarse, earthy green is similar in color to a pistachio.

The quite frequent mineral epidote is a calcium iron-aluminosilicate with a complex chemical structure. Epidote is often found in hard, lustrous pistachio green or beautiful dark green prismatic crystals. Since the difference analysis between the different kinds of green earths is quite difficult to undertake, it is usually not clear which kind of green earth exactly is present in a specific historical picture, which, in most cases, makes a reliable attribution of epidote very hard. However, this green to yellowish-green pistachio colored pigment might well be the dominating pigment in many depictions of yellowish green meadows from the early gothic times. Epidote is found in many places worldwide. The largest European sources for epidote are the Piedmont region in Italy, Austria, Russia, Elba Island (France), and Tuscany (Italy). The epidote from Kremer Pigmente comes from a volcano schlot in Arizona, USA.
