This is powdered natural indigo from our Tennessee farm!
Approximate purity 40% for powder.
Paste is made to be a consistent, easily solubilized liquid of approximately 13% indigotin.
For dyeing dark blues on cotton and other cellulose fibers, we like the ferrous (iron) vat or fermentation vat as explained in Jim Liles' book "The Art and Craft of Natural Dyeing"
