Here's a quick top-of-the head idea: Adding strong magnesium sulfate solution to a solution of mescaline citrate - would that potentially precipitate mescaline sulfate crystals through the common-ion effect? Sort of like a Manske for mesc.. This seems so simple that surely someone would have discovered it by now if it worked
It's all about which are the least and most soluble of:
Mescaline citrate; magnesium sulfate
Mescaline sulfate; magnesium citrate
I'm a teeny bit surprised to hear of benzyme (of all people) attempting to evap sulfuric acid. At 1 atm it boils at 338°C, What kind of hard vacuum are you pulling to get rid of that in a water bath?!
βThere is a way of manipulating matter and energy so as to produce what modern scientists call 'a field of force'. The field acts on the observer and puts him in a privileged position vis-à-vis the universe. From this position he has access to the realities which are ordinarily hidden from us by time and space, matter and energy. This is what we call the Great Work."
