Wondering if I should go and knock up a refill for the chlorine gas generator I have rigged up outside in the garden and start gassing the remaining iodine in the column its connected to, now I know I've unstuck the receiver flask that the resulting iodine monochloride is distilled over to. Or if its too late. Don't want to do that in the dark, I need to see what I'm doing, since it is a somewhat hazardous procedure, chlorine gas isn't too healthy to breathe, iodine monochloride vapor is worse by a long shot, although it is somewhat unstable to air, IIRC breaking down to Cl2 and I2 vapor somewhat readily. Still, buggered if I'm doing it in the dark and risking poisoning myself.
