Lake pigment

A lake pigment is a pigment made by precipitating a dye with an inert binder, or "mordant", usually a metallic salt.

The resulting pigment is called a lake pigment.

Some dyes can be rendered insoluble with the addition of salt to produce a lake pigment.

The dye lake is an insoluble complex formed upon combining the dye and mordant, which then attaches to the substrate.

Rose madder is the commercial name sometimes used to designate a red paint made from the pigment madder lake, a traditional lake pigment extracted from the common madder plant Rubia tinctorum.

Carmine ( or ), also called cochineal, cochineal extract, crimson lake or carmine lake, natural red 4, C.I. 75470, or E120, is a pigment of a bright-red color obtained from the aluminium salt of carminic acid; it is also a general term for a particularly deep-red color.

Kermes carmine was used as a dye and a laked pigment in ancient Egypt, Greece, Armenia and the Near East and is one of the oldest organic pigments.

It is named after the organic dye alizarin, found in the madder plant, and the related synthetic lake pigment alizarin crimson (PR83 in the Color Index).

Unlike vermilion, ultramarine, and other pigments made from ground minerals, lake pigments are organic.

Many lake pigments are fugitive because the dyes involved are not lightfast.

Red lakes were particularly important in Renaissance and Baroque paintings; they were often used as translucent glazes to portray the colors of rich fabrics and draperies.

The term "lake" is derived from the term lac, the secretions of the Indian wood insect Laccifer lacca (formerly known as the Coccus lacca).

Many lake pigments are azo dyes.

They characteristically have sulfonate and sometimes carboxylate substituents, which confer negative charge to the chromophore (colored species).

In ancient times chalk, white clay, and crushed bones were used as sources of the calcium salts.
