Hello OBG,
These are close but not exactly what I'm talking about. The genuine crystals are what the special forces use in the jungle wher you might encounter any number of harmful pathogens. I understand that they are hard to find because they are also used in the manufacture of certain illicit drugs. The Crystals I am looking for used to be available at any chemical supply. They are called resublimated iodine crystals.
Thanks for the help!
