Description
Another rare oil paint you will struggle to find anywhere else!
Blue verditer or bice is the name given to an artificial copper carbonate, it has approximately the same chemical composition as azurite and behaves and looks quite similar to its colour cousin. This is a very rare and unique paint.
The hue in masstone is a bright blue, and the pictured swatch appears somewhat duller than the reality.
It will add a cool brightness to mixes and produce wonderful greys on a portrait palette. Gentle in tints, producing bright sky blues. Good lightfastness.
A little extra information from Wallace Seymour;
"Made in small batches to our recipe. CuO + nH2O. An artificial copper-calcium carbonate pigment, a synthetic version of azurite. In manufacture, copper nitrate is mixed with chalk, or precipitated from copper sulphate in solution, in combination with ammonia and lime paste. During preparation, if the temperature becomes too warm, a green shade develops (green verditer). In England, verditer pigments were formerly manufactured in Sheffield, Yorkshire. Blue verditer was important in wall decoration during the 1600s and 1700s and also used on a small scale in easel painting. Current production is made to our recipe in Nottingham, England."
