Discovered in 1830 in Russia, Volkonskoite (No Index) was named after Volkonskiy, Russian Minister of the Imperial Court, Field-Marshal-General in the war of 1812 against Napoleon. Volkonskoite as a mineral is formed in result of reaction chrome enriched groundwater with organic remaining of wood. It’s a very rare mineral deposited primarily in Russia.
Artists value Volkonskoite as a pigment providing olive translucent colour, which makes it perfect for glazing. After drying Volkonskoite is very stable and keeps its colour for life. That’s one of the reasons of using it in icon painting. Also Pablo Picasso liked this pigment for its beautiful color and features.
Volkonskoite is available at Rusart Art Supplies in Master Classes series.
