How to use weld extract:
Make a paste with 1 teaspoon (5g) weld extract and a small amount of warm water. Fill a saucepan with water and add the weld extract paste. Mix about one third of a teaspoon of chalk (calcium carbonate) with a small amount of boiling water in a container and add to the pot with the weld.
Bring the dye bath to a gentle simmer and maintain at this temperature for 45 to 60 minutes, stirring gently from time to time. Leave overnight to cool.
Weld is a knockout yellow colour, 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 colour.
