INDIGO CRYSTALS(Indigofera tinctoria): Truly indigofera tinctoria, not a laboratory-produced synthetic indigo, nor is it indigo extract.
It is processed in Japan by a secret extraction and fermentation method, freeze-dried to make it the easiest indigo ever to use. Just add the crystals to warm water, thiox and soda ash, stir, wait a few minutes (not hours) and it’s ready to use for vat dyeing or hand-painting.
Best on cotton, linen; good on other fibers. This is a beautiful blue dye and pigment, but for manuscript illuminations, a few grains will go a very long way! Indigo in any form is very light- and wash-fast, but not abrasion resistant. Mordants will not change colors, but only affect the shades of blue that can be obtained. See the PIGMENT department for more information.
AKA: Freeze-dried indigo, instant indigo, pre-fermented indigo, pre-reduced indigo, processed indigo. [Japan]
