Synthetic colorants, c 1900.

GERMANY - JULY 28: Six jars containing synthetic colorants. Blue Lilac 20 manufactured by G. Siegle & Co. of Stuttgart; Guinea-Rot (red) SDG by Actien Gesellschaft für Anilin Fabrikation, Berlin, Germany (Agfa); Ultramarine 9 by Siegle; Guinea Echtgelb 3G by Agfa; Imitation Vermilion 3 by Siegle; Vermilion 00 by Siegle. The Guinea dyes were introduced by Agfa in the early 1880s. Ultramarine (blue) and Vermillion (red) are traditional pigments. Ultramarine is a natural blue mineral which is rare but ultramarine has been made synthetic since the early nineteenth century. Vermilion is a red form of mercury (II) sulfide (as in the ore cinnabar). The Aktien Gesellschaft für Anilin Fabrikation was founded in 1873 by Carl Martius and Paul Mendelssohn-Bartholdy (the nephew of the composer), became part of I.G. Farbenindustrie AG in 1925 and a subsidiary of Farbenfabriken Bayer AG in 1952. In 1873 the Stuttgart firm Heinrich Siegle was acquired by BASF. In 1889 Gustav Siegle (the son of Heinrich Siegle) bought the buildings back and started the production of mineral pigments and lacquers. Part of a collection of late nineteenth and early twentieth century colorants transferred from the Colour Museum, Bradford, in 1985. (Photo by SSPL/Getty Images)
