When high firing glazes that have no more than 2% of the following, is it
safe for food or drink? I have heard and read where this is okay. Just
want to be sure!
The amounts I am wondering about are anywhere from 0.5% - .75%?

manganese dioxide
tin oxide
copper oxide
cobalt oxide
cobalt carbonate

I would appreciate it greatly...Poor Ron Roy, I have questioned him to
death already and cannot bear to ask him anymore!

Thanks !
