Textile dyeing : the natural indigo dyes provide ranges of blue shades, from very clear to dark, with a very good lightfastness and washfastness. Their use in textile needs to turn them from an oxidized state (blue pigment, insoluble) to a reduced state (greenish yellow pigment, soluble) which will allow to fix on fibers before being again oxidized (by the oxygen of air – a magic step that develops the blue color). These reactions can be processed in natural vats by using our fructose syrup and hydrated lime for instance (1-2-3 vat type) or by using a chemical reducing agent (sodium hydrosulphite or thiourea). The natural indigos can be easily combined with other dye extracts (yellow, red for example) to widen the range of shades (green, purple…).
Instructions and downloads : Preparation of indigo vats & dyeing instructions, advanced information on indigo natural vats (only in French, sorry).
Paintings, decoration, fine arts : the indigo is then directly used as a natural pigment, after homogenizing into the selected binder or medium. It may be necessary to grind the pigment into the medium in order to develop the colour and avoid big particles.
Other uses : cabinetmaking, ink.
