Rose madder

Statue under normal lighting conditions

Description

A natural dark pink madder colorant. Rose madder became popular as an artist pigment after the madder plant was imported to Holland in the 16th century. The colorant was extracted from madder roots with an acid, then the precipitate, primarily pseudopurpurin, was redissolved in alum then reprecipitated with calcium carbonate (chalk) to produce a pink lake (Schweppe and Winter 1997).
