Specialty shops for home wine-making will carry fumaric acid.![]()
Pickle, it should be noted that the first two teks you listed are essentially the same. They're both STB. The only major difference is the freeze precipitation step, which I consider essential. Simply evaporating the naptha will yield a much dirtier product.
Also, the last one you listed will yield dmt fumarate, which isn't really usable by vaporization.
I did another extraction on that North Brazilian MHRB and I got a 1,58% yield after freeze precipitation.
On the other hand, I'm having trouble producing pure white spice. It is snow white when I pour off the naphtha after recrystallization, but by the time it dries (I leave it to air dry for 12-24 hrs.) it is already off-white.
i can't smoke it you mean?????
