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/
