Natural Indigo, ground, Indigo tinctoria
Indigo is a perennial grown in semi tropical climates and at one time indigo plantations existed in the southern U.S.
Indigo will not dissolve in water. Therefore the dyeing process is different from other natural dyes. It is sometimes referred to as a vat dye.
Historically, Indigo was an important dye in over dyeing yellows to produce green which is a color difficult to obtain in natural dyeing.
Refer to a natural dye book for more details.
Although many dyers do not use mordants for indigo, we recommend them. Colors obtained will vary due to mordant and water ph.
The mordants used in the yarn samples in the picture are left to right as follows alum, tin, iron.
There should be enough to dye two or more pounds of fiber.
Item purchased is the plastic bag of ground indigo in the picture.
