Weld Extract – Weld (Reseda luteola) is the most lightfast of the yellow dyes, used by ancient tapestry weavers in Central Asia, Turkey and Europe. Weld is the brightest and clearest yellow flower dye. In combination with iron, weld creates a rich chartreuse, or when overdyed with indigo yields a clear lime green. We carry a very fine grade of weld extract that is also certified for organic textile processing in compliance with the Global Organic Textile Standard (GOTS). Directions for use included. For best results, use at .5%-3% weight of fiber (wof). Adding a pinch of soda ash and calcium carbonate to weld while you are dissolving it deepens the shade and the color yield from the dyestuff. Leftover dye baths create a lemon yellow shade.
- 25 g of Weld extract will dye approximately 800 grams (1.75 pounds) of fiber to a dark shade
