 and ancient Corinth. It was included in the Talmud as well as mentioned in writings by Pliny the Elder, and other literary figures, as 'rubio', used in paintings by J. M. W. Turner, and as a color for ceramics remnants of its use have been found at the Baths of Titus. Madder was introduced and then cultivated in Spain by the Moors. It has been found on an Egyptian tomb painting from the Graeco-Roman period, diluted with gypsum to produce a pink color.

The production of a lake pigment from madder seems to have been first invented by the ancient Egyptians. Several techniques and recipes developed. Ideal color was said to come from plants 18 to 28 months old that had been grown in calcareous soil, which is full of lime and typically chalky. Most were considered relatively weak and extremely fugitive until 1804 when the English

 and the more rapidly fading purpurin. Purpurin is only present in the natural form of madder, and gives a distinctive orange/red generally warmer tone that pure synthetic alizarin does not. Purpurin fluoresces yellow to red under UV light, while synthetic alizarin slightly shows violet. Alizarin was discovered before Purpurin, by heating the ground madder with acid and potash. A yellow vapor crystallized into bright red needles: Alizarin. This alizarin concentrate, makes only 1% of the madder root.

Natural rose madder supplied half the world with red, up until 1868, when its alizarin component became the first natural dye to be synthetically duplicated by Carl Graebe and Carl Liebermann. Advances in the understanding of chemistry: chemical structures, chemical formulas, and elemental formulas, aided these Berlin based scientists in discovering that alizarin

 base. However, their recipe was not feasible for large scale production; it required expensive and volatile substances, specifically bromine.
William Perkins, the inventor of mauve, filed a patent in June 1869, for a new way to produce alizarin without bromine. Graebe, Liebermann and Heinrich Caro filed a patent for a similar process just one day before Perkins did- yet both patents where granted, as Perkins had been sealed first. They divided the market in half: Perkins sold to the English market, and the scientists from Berlin to the United States and mainland Europe.

Because this synthetic alizarin dye could be produced for a fraction of the cost of the natural madder dye, it quickly replaced all madder-based colorants then in use (in, for instance, British army red coats

Substitutes

As all madder-based pigments are notoriously fugitive, artists have long sought a more permanent and lightfast replacement for Rose Madder and Alizarin. Recommended alternative pigments include:
  • Benzamida Carmine (PR176)
  • Quinacridone Pyrrolodone
  • Pyrrole Rubine (PR264)
  • Anthraquinone red (PR177), a chemical cousin of Alizarin
  • Quinacridone Violet (PV19), particularly dark and reddish varieties
  • Quinacridone Magenta (PR122), for a brighter violet
  • Quinacridone Rose (PV19), for a brighter violet
  • Perylene Maroon (PR179], for mixing dull violets
