I unearthed my old Procion dye powders and such and have two bags, unmarked of course, of white granular substances. Given my crummy memory at the best of times, I was wondering if any of you hand dyers out there could tell me which chemical was which, considering one has clumped together into a rock and the other is free-flowing. Urea and soda ash are the choices. Any ideas?
