Whole Madder Root – Rubia cordifolia from India. Very strong and rich reddish orange shades with multiple afterbaths. Use the Whole Madder Root-Rubia Cordifolia waste for fermented indigo vats or for composting. We like to soak the roots, grind or pulverize, then add fiber and simmer at low temperatures to develop the deep rich color. We use 100% on the weight of the goods for deepest cranberry to garnet shades. A small amount of Citric Acid and Calcium Carbonate allow you to get the richest shades from our madder roots. Don’t throw away the spent roots. You can dry them and use in eco printing or for fermentation indigo vats, or even rehydrate for a second, paler dye bath.
For deepest shades, use madder root at 100% weight of fiber, or use less for paler coral and orange shades. Soak in cold water for several hours, or overnight, to soften roots. Use a large volume of water as the madder swells and expands. If you want to avoid having madder root particles attaching to the fiber, you can enclose the ground roots in a mesh bag as you soak them.
- 250 grams of Whole Madder Root-Rubia Cordifolia will dye 250-1000 grams (7 ounces to 2.2 lbs) of fiber. More madder means a darker shade up to a 1:1 ratio.
