Is this glaze “Food Safe”? One of the main questions asked by our customers.
The term “Food Safe” cannot be applied to a glaze (as supplied).
Only the final cooked piece can be considered "Food Safe", it is something that is beyond our control and that of any supplier as it depends on a huge variety of factors impossible to control. The paste itself, shape and texture, oven and cooking, added oxides are some of the variables to consider for a product to be “Food Safe”. However, the only way to guarantee that you have a piece that is considered "Food Safe" is to use a certified ceramics testing laboratory to certify it.
