Cutch Dye-Bath in progress. Cutch/Catchu is an Acacia species grown throughout the tropical/subtropical world. Its wood yields a warm, reddish-brown tannin.
Indigo – Hydrated pigment powder; submerged/partially-unoxidized and oxidized color. Unlike other natural dyes, Indigo color is achieved through a reductive/oxidative chemical process.
Surrounding the familiar seeds, Pomegranate Rind, alas, does not yield a rich red as one would expect but rather, a mellow yellow.
Black Walnut Hulls
Black Walnut (Juglans nigra) is tree species native to the Eastern United States. The hulls surrounding the nut are prized for their soft brown tannin. The hulls are also used to prepare a ink for drawing and painting.
