Description
In partnership with the company Pastel de la Serre, we offer this woad indigo in paste. This pigment 100% natural is obtained from fresh leaves of woad (Isatis tinctoria L).
It is manufactured locally, from woad plants grown and transformed in the South of France, 1,5h from our place – in the historical “triangle of woad”.
A product tracked with a good quality. CAUTION : PIGMENT IN PASTE – LIMITED QUANTITY

Use : Textile dyeing : the indigo dye provides ranges of blue shades, from very clear to dark, with a very good lightfastness and washfastness. Its use in textile needs to turn it 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 (1-3-2 vat type). The indigo can be easily combined with other dye extracts (yellow, red for example) to widen the pallet of shades (green, purple…).
