This is powdered extract of fresh leaves of Isatis tinctoria, also called woad (/wod dyer’s woad, or Jerusalem Asp. in France it is called pastel & in German Waid. in Dutch we call it wede. Woad pigment can be used for natural dyeing, for soapmaking & for candle making & will produce light blue to deep blue shades. It is a flowering plant in the family Brassicaceae, a biennal herb up to 1.60 meter tall. Woad is also the name of a blue dye produced from the leaves of the plant. Woad contains indigotin, in the form of isatan A & B but in lower percentages than the regular indigofera plants. You have to make a woad vat in order to use this powder, you can combine woad with indigo. For the samples I created a simple hydros vat using the free instructions of my blog with 10 grams of woad powder per liter water. 100Gr | 3.7 Oz Woad Extract - Isatis Tinctoria Natural Blue Pigment For & Indigo Vat Soap Making
