not really a question but an answer here, this might be useful info for recrystalizations and maybe extracts. i have done several recrystals with an overload of spice....2 g's in a shot glass and 20 ml's of heptane warmed to near boiling temp, with a freeze precip after and found that 20ml of heptane will consistantly hold .25 to .35g alot of people may have already known this but hey if im wrong let me know
