if you used kM04 and CuSO4*5H2O to oxidize your ephedrine this blueish tint might be extra CuS04*5H2O... just dependes on your methode.. more info maybe?? "Vanity is defintely my favourite sin" -Devil's advocate |

wash | Bookmark | ||||||
washed in cold acetone, and filtered several times. wash held blue color, crystals white as usual after drying. burn on aluminum foil shows quick melting, no ash, minor yellowish discoloration left on foil. odd burning hair smell, but otherwise appears normal. good yield also.
