Just wondering about Philippes suggestion: an aspirine i.s.o. formaldehyde or equivalent.
If so, how much? Is one 500 mg tablet enough for one liter gum?

>> I have a very fine gum powder and need a little direction in preparing the solution. I know I've asked a similar question before and Chris Anderson mentioned something about a blender. I made a solution a few months back when I bought the materials, but had a little sojourn in the States and it has since turned on me (no thymol access). When I prepared it, it came out very dark and murky, though I've heard this isn't much of an issue. But I can't help but wonder if I was doing something wrong in the first place. The product I have is Lobachemie (from India) Acacia powder...no other details.
