Fustic – Fustic (Chlorophora tinctoria) is a tall tropical hardwood that grows from Mexico to Argentina. Fustic is high in tannic acid, which makes it an ideal cotton dye; in fact, it was used in the military to dye the color khaki during World War I. On cotton, it will dye a clear gold and on silk and wool it will dye gold to orange. Fustic also provides a good base for other colors: overdyed with indigo for green; combined with madder and cochineal to make oranges; and mixed with logwood or with iron to produce olive greens. Our fustic extract is in liquid form and is very strong. Use at 1-10% for bright to rich gold.
- 50 grams of Fustic extract will dye approximately 700 grams of fiber (25 ounces) a medium gold shade
