Scope note
Translucent golden-colored resin composed of a yellow resinous component and a clear water-soluble gum, produced by several trees of the genus Garcinia native to India, Thailand, Cambodia, Vietnam, and Sri Lanka. Gamboge was used as a yellow pigment as early as the 8th century in Asia and Japan. It was regularly imported to Europe in the 17th century. It is marketed in the form of dull, brownish-yellow cakes or lumps that, when powdered, have a rich golden color. The carbohydrate gum acts as a natural binder. Gamboge is used as a transparent colorant in glazes, varnishes, and watercolors. The yellow color fades when exposed to light or ozone. In some cases it has recovered its color when placed in the dark.
