Cutch powder is derived from Acacia trees and contains tannin. It is a substantive dye (does not need a mordant to bind to the fibres in a fabric). When used on its own, achieves shades of grey-brown. After soaking in a dilute solution of ferrous sulphate (Iron mordant), known as saddening, it will produce dark shades of brown to black and a khaki brown with Copper mordant. An orange tone can be achieved when Titanium Oxalate is used as the after-soak. It is possible to prepare cellulose fibres and fabric such as cotton and linen, by cycling Tannin with Alum for setting Natural Dye colours. 100g bag
