A nineteenth-century magazine article on magenta (fuchsine, aniline red), tracing its manufacture from coal-tar through benzol, nitrobenzol and aniline oil to the arsenic acid oxidation process. It then describes dyeing silk and wool with magenta, with tips for even shades, and dyeing cotton using tannin mordants or animalizing agents. It closes with methods of printing magenta on animal and vegetable fibres using albumen, tannin or caseine.
