wow ... all the kitchen chemists whip out their note pads, quick ! ...! - I must go re-read all that.. ! So then could the yellow MHRB extract have traces of Yuremamine in it, explaining why (swim says) sometimes it's a different experience with yellow, oily crystals..? I always marveled at how filtered, aqueous acidified MHRB is so beautifully burgandy-red; it always been my favorite part to watch when swim does it ! It glows like a cherry-wine, but transparent - and invisibly dissolved in a jar you have all the extracted magic. With MHRB, think of all the colours it goes before being pure spice... purple first, then it goes grey, then jet-black then yellow or transparent-white ... in the end the white crystal is the yeild with highest purity. All drawn from a blood-wine coloured staring point. There's gotta be many more alkaloids lost from that purple acid extract... made cold or hot... many toxic too... no..? Once I was using diethyl ether to put fruit flies asleep ! ... what an amazing solvent diEty is !(...genetics experiments...) ...
