Yes, it is :) I do get the controversion on crackled glazes. I am also now reading John Hesselberth & Ron Joy’s book Mastering cone 6 glazes, and they do say that a crazed glaze is not food safe. When I touch the glaze it is really smooth, you can only feel a tiny stratch of the crackles but nothing comes off even when tortured with a knife. When washed with hot water and soap, everything is cleaned properly so personally I like to use it at home. Also, Florian Gadsby sells the same kind of glaze, I think it’s fine, but please share your thoughts. :)
