Description

A natural, yellow dyestuff produced from a boiling water extract of wood chips from the dyer's mulberry, Chlorophora tinctoria or Maclura tinctoria, trees. The dye was imported into Europe in 1510 from the West Indies, South America and Central America. Dye colors can range from a pale yellow with alum to a dark tan with copper. Soaking the wood for long periods produces a stronger color. Fustic contains the yellow flavonol colorant morin. Morin will react with aluminum to produce a green fluorescent compound. Fustic produces a slowly fugitive, bright yellow coloring that is used as a textile and leather dye, wood stain, a varnish colorant and a lake pigment. It is often mordanted with chromium salts.

(This is not the same dye as young fustic.)
