"the sulfate salt...has a miserable melting point (it contains water of crystallization, and the exact melting point depends on the rate of heating of the sample) it nonetheless forms magnificent crystals from water. Long, glistening needles that are, in a sense, its signature and its mark of purity." -from PiHKAL, entry on Mescaline I received an order of what the dealer claimed was mescaline sulfate, but it was in the form of white powder, not crystal needles. Should I be concerned about the purity?
Ground/crushed, I'd expect. who would ship/carry sketchy looking space wasting crystals? You can try re-crystalizing it if you don't trust your connection. From what you posted, I think you should just be able to dissolve it in distilled water, and evaporate it, to see.
I have heard of mescaline powder. Honestly I don't think you'll be able to tell by appearance. Cocaine and scopolamine look identical, one will give you 30 minutes of dopamine euphoria, the other will send you into full delusions and possibly kill you. Like any substance you receive proceed with caution as it really could be ANYTHING. If your really THAT concerned about it the only true way of knowing is to get it analyzed by a lab. Now what you can test it by is its properties: Mescaline Sulfate Appearance: prisms Melting point: 183–186 °C (361–367 °F) Molecular Weight: 309.33606 Soluble in: hot water, methanol Almost insoluble in: near freezing water, alcohol, acetone Check its solubility in what ever of those you got! If after that you believe it to be mescaline, then re-crystalize that ish Regardless, like every new batch of substance you get start with a very minuscule amount as a precaution and work up from there.
What is your source on that info? Others have told me that mescaline sulfate SHOULD be soluble in alcohol, say 80 proof. It would actually be really helpful to know that answer for sure since I had been planning on dissolving in alcohol for purposes of liquid dosing.
My source is the book The Hallucinogens, by H. Osmond and A. Hoffer. - Pg 17, Paragraph #3 It appears that the freebase is soluble in ethanol but not the sulfate. Hope this helps!
