so we know that hcl and sulphates yield nice final products, but what about fumarates?
i theorize that if one salted with fasw and evaporated thier product they would be left with both mescaline fumarates and excess fumaric acid. since mescaline salts are readily dissolved in rt water i would follow the same idea that dmt fumarate uses as a clean up, minimal water.
slowly (drop wise) add water to your fumarates+fumaric acid until nothing more seems to dissolve, since fumaric acid is a bit more difficult to dissolve in water, let alone minimal water already saturated with something, it seems this method would effectively salvage the mescaline from the majority of the acid contaminates
the dmt clean up calls for 12 ml per g of fumaric dmt + fumaric acid, this method works well and might be a key to cleaning mescaline fumarates aswell...
if anyone has experience salting mesc with fumaric acid and or cleaning up please post some of your thoughts
