After taking account of vessels containing a certain bright yellow, crystalline and although not actually itself illegal, most certainly rather naughty material, found out that including the two I was well aware of, there's actually about 7 or 8 fair sized batches that are in need of recrystallization and being turned to other naughty, and if it were buyable for a private individual at all, VERY tightly watched goods, that again, isn't illegal, but a certain ketone, or it's corresponding ketoxime that has rather a lot of financial value for an unwatched, untraceable quantity.
Haven't been able to weigh it all, since some is in solution, and the various lots are of differing purity, so I wouldn't mix them all up in one big batch, but I was actually quite surprised by the quantity around. Methinks I ought to get round to purifying and recrystallizing as much of that as possible, hopefully I can get around to it today if I can find the motivation.
