My books say that weld gives a strong yellow. I chopped up 2 pounds of weld plants but one 4 oz. skein (alum mordant) is only giving a very pale color soaking overnight . Does it need heat? Anyone have experience here?
My method - which most dyers would tell you is incorrect - is to heat the plant matter in some water to just under a boil. Turn off the heat and wait until the next day. If the water is colourful (it doesn't need to be yellow, just have some sort of colour), then I strain out the plant matter (keep the water) and then repeat the process with the yarn.
I've read that weld is very sensitive to PH and temperature, so I think it would be good to treat it like we do madder - trying the lower temp first, then trying higher temperatures later.
