Madder Root, Rubia cordifolia, Ground Powder
Price is per ounce.
Rubia cordifolia powdered roots make dyeing with this traditional dye easy because the roots are completely ground to powder. You can use a nylon stocking or a mesh sac tied with string to contain the powder if dyeing yarns. Warm the water and stir the roots for 5-10 mins, add fiber and simmer (between 185-200 degrees max) to develop a dark red. Madder root is dyed at 35-100% WOF for a medium depth of shade. If your water is soft, add Calcium Carbonate at 2% on the weight of the goods dyed.
