TABLE 4-5 (continued): Recommended supplemental chemicals and quantities

ATIodBoU INE

Just before this book went to press, the DEA reclassified

elemental iodine in any quantity as a List I chemical,

because iodine is sometimes used by illegal meth

labs. Although it is still legal to purchase elemental

iodine,many suppliers no longer offer it because of the

paperwork involved.

If you can’t find elemental iodine for sale (or if you

just don’t want your name to end up on a DEA list) you

can make your own iodine crystals from potassium

iodide. For instructions, visit http://www.homechemlab.com/
