Natural indigo blue dye

Natural indigo blue dye (Indigofera Tinctoria)

Made of indigofera tinctoria extracts, the cut plants of indigo are packed in the fermentation Vat and filled with clear fresh water and allowed to sleep still the rapid fermentation for about 10-15 hours, then transferring the liquid into another vat for oxidation where the color of the liquid turns from green to blue and finally the indigo separates out as flake and precipitates to the bottom of the vat, when the supernatant liquid is drawn off. The pulpy mass of indigo is boiled, filtered and pressed to remove as much of the water as possible, after which it is cut into cakes and finally air dried.
