Aniline black

Description

A black dye that was patented by J.Lightfoot in January 1863. Aniline black is composed of oxidized aniline hydrochloride. Fabric, such as Cotton, is soaked in an aqueous solution of aniline hydrochloride and an oxidizing agent, such as Chromic acid. This results in a strong black color that is not lightfast. Aniline black was also added to iron gall inks to produce a strong, initial black color. Once the aniline black faded, the iron and gallic acid color had developed a strong black tone (Kuhn 1986).
