Based on Liles recipe
Ingredients:
1 lb weld (Kremer weld)
1 lb wool
3 oz alum
1 oz cream of tartar
Process:
Boil the wetted wool in the alum & tartar for an hour. Rinse.
Put the weld in 2.5 gallons of water. Simmer for 1 hour and strain. Add enough water to bring it to 4 gallons. Enter the wetted wool and boil for fifteen minutes.
Because the wool was such a drab yellow, I added 1/4 c lime after fifteen minutes. This made the fabric darker, and the dyebath brown.
Notes:
I was disappointed with the color. Not as deep and intense as I thought it should be, but rather a cold mustardy yellow. The lime ended up dulling the yellow. It smells like rotten eggs.
Next time: add some fustic, and experiment with a quick-lime afterbath. Look into a lye-based dye vat. Try a different brand of weld.
