>>I wonder if iodine is corrosive to aluminum. <br><br>I just spoke with my smart sibling (Ph. D. in organic chemistry from U.C. Berkeley!!!) who says that in their lab, iodine was always stored in big brown glass bottles. She pulled up a webpage ( www.fpsmith.com/sscorrs.htm) that shows the corrosiveness of substances with stainless steel. Apparently iodine is very corrosive. She didn't know if this would cross over to aluminum. She suggested a brown prescription pill bottle *might* be an option if wrapping the brown glass bottle with tape doesn't pan out.<br><br>She freely admitted that she's no metallurgy expert, so take all this with a grain of (iodized) salt (sorry, I couldn't resist!).<br><br>Just my two cents' worth!
