This dye is extracted from plants of the genus Indigofera, beloging to the Fabaceae family and especially from the suffructicosa mill species.
Indigo colour was used in Mesopotamia and by the ancient Greeks and Romans (the Greek word Indikon means “Indian substance”). In the 13th C. Marco Polo was the first to document the fabrication process of indigo dye in India.
The plant was brought to Europe by Vasco de Gama in 1498. For many years it was considered as “the king of dyes”, and it is what gives blue denim jeans their colour.
The chemical compound is called Indigotin. The German chemist J.F.W. Adolf Von Baeyer was the first to synthesise it in the laboratory in 1880.
