This seems pretty questionable... You are gona pop off all this speed without alerting your ROOMMATES? Sometimes I worry about alerting the whole block! Have you every smelled methylamine?! You better know what you are doing on the first run... And Limitless is right, you wont be able to make shards with your racemic stuff. The biggest grain size you can hope for is about sea-salt size. Atleast not without some chemistry tricks that are above your pay-grade. Oh thats right you read about fractional crystallization before and are totally confident doing it in real life. I don't want to be a downer but don't hold your breath that this guy is gona pull off his first large scale synth in the bathroom nextdoor to two unknowing roommates. Diving into a project like this is the best way to learn, but don't lead on all these folks. You are kinda counting your chickens before they hatch.
