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?

Urea is usually sold in little pellets, while soda ash is in coarse grains.
The easiest way to distinguish them is to drip a little vinegar on a sample. Urea will just sit there while soda ash will bubble like crazy.
