Vernis d´huile, jaune brun

Cooked resin oil varnish with madder lake.
Madder lake is an anthraquinone originally derived from the root of the madder plant. It became the first natural pigment to be duplicated synthetically. Madder lake was used in ancient Egypt, Greece and Rome for dyeing textiles and, to some extent, for making pigments. Synthetic alizarin was first made in 1868. In the following years, madder lake was superseded by alizarin crimson, a pigment superior to it in every respect. Synthetic alizarin did not replace natural madder immediately. Today, most painters prefer alizarin, but a few artist colors made from rose madder can still be found among the European brands.
