When a manufacturer states that a specific line of glazes is 100% mixable, and that each of these glazes is food safe on its own, can I assume that means that if I layer or mix colors in the same line the glaze is still food safe? Applied and fired according to their instructions of course.
I'm really agonizing over glaze safety and no, I don't want to make my own glaze. The prevailing wisdom, and what the manufacturer's say, seems to be that once different food safe glazes come in contact with eachother, all bets are off as to the food safety of that glaze. This makes sense to me, but I'm seeing all sorts of combining going on in utilitarian ware. Beautiful combining. I don't think everyone is sending their stuff off to the lab for testing. Or maybe I'm wrong. At this point I'm using single glazes anywhere food touches.
I'd appreciate any guidance and suggestions.
