Weld Extract-Weld (Reseda luteola) is a knockout yellow color, and the most light fast of the yellow dyes, used by ancient tapestry weavers in Central Asia, Turkey and Europe. Weld is the brightest and clearest yellow flower dye with a distinct green cast, from which an electric lime green is possible in combination with indigo. Our powdered weld extract is extremely potent, and benefits from either adding calcium carbonate to the dye bath, or a post bath of ammonia to brighten the color.
.25 oz. of Weld extract will dye approximately 8 ounces of fiber to a dark shade.
