Indigo Can Be Extracted From A Plant And Then. To the best of my understanding the book focuses on working with Indigfera tinctoria or a related Indigofera genus plant. Natural indigo is often produced in small rural communities where the origins can be.
Indigo precursors found in plants. The Indigo plant was the most widely available plant for producing dye and can be grown in many regions of the world making it an easily accessible resource. Suifruticosa are the most common.
If this limitation can be overcome at scale demand for natural indigo in Northern California is already ample with one textile mill expecting to dye enough material to require about 2 5 to 4 acres of indigo if using the compost process.
Color of the mass changes into green then blue and then into the indigoMass settles to the bottom of the vat and is then extracted. In the dyeing process when a textile is dipped in and then removed from the vat the indigo molecules on the fabrics react with oxygen and then revert back to their original state regaining their blue and sticking between fibers. The amount of indigo dye that can be extracted from plant material is relatively small and varies from report to report. Tinctoria indigo is hardy in USDA zones 10 and 11 where it grows as an evergreen.
