Bethw13 got a reaction from Tyler Miller in Manganese Dioxide
Why use it at all? There are so many glazes, stains, etc, why use something that you know can be toxic to your customers??
Ok if you want to take the risk, but to subject other people to it?
I know most oxides are dangerous and toxic, make sure your glazes are able to contain the toxicity to use the chemicals. Research and test.
