The Story Behind Indigo Dye Fermentation
In short: Indigo dyeing relies on a chemical reduction process that converts insoluble indigotin into soluble leuco-indigo, which then oxidizes back to blue upon air exposure; this ancient process, once natural, now faces modern environmental challenges demanding sustainable chemical alternatives.
