The folks at Kordon are sending me some samples of their breathable bags, which are used for shipping tropical fish. I will conduct a similar experiment to the oven bags as a comparison. I suspect that the oven bags will be a preferred choice simply becasue of availability. The Kordon bags are not avalable through retail channels yet.<br><br>An interesting aspect of the breathable bags is their ability to pass oxygen and carbon dioxide through the palstic. (all plastic bags do this but to a much lesser degree.) I recall reading that oxygen plays a part in the chemical reaction with iodine in the tablets. Would the Kordon bags have an impact on this process? Or doesn't it matter?
