I took a ceramics class and no one could tell be what the glaze was made of and if it was non toxic. I was making some fun bowls and mugs. You just reminded me, are the store bought glaze mixes toxic? Please share how your wife finds or makes non toxic glaze. Also does firing ceramics in a kiln release even more toxic chemicals in the finished ceramic?? I’ve always suspected this was inherently creating some toxic byproduct from the intense heat. Thanks!
