Description

Rublev Colours Cobalt Violet

The remarkable range of pigments that could be produced with cobalt included cobalt violet, is known since 1859. Salvetat first described the preparation of cobalt violet in Comptes Rendus des Seances de l'Academie des Sciences XLVIII in an article titled, "Matieres minerales colorantes vertes et violettes." The dark variety is anhydrous cobalt phosphate which was made by mixing soluble cobalt salt with disodium phosphate. It was washed and then heated at a high temperature.
