I'm not worried about the food safe aspect, I rarely make any thing that is used for food or drink.  I mostly work in tile, sculpture and pots.  If someone wants me to make them mugs or plates I'll use a purchased glaze that is food safe.  I am very cautious when it comes to safety, I have even been known to question a manufacturer about a glaze that has been labeled food safe that seems kind of iffy.    Denice

I keep forgetting to say this glaze was not tested as "food safe" but since I plate my pots with a copper solution in a sulfuric acid bath for at least 2 days, I don't think that lemon juice will effect it.

Thanks for posting that glaze, I'm going to be doing dome testing soon I plan to give it a try on the Laguna speckled buff and Flinthills buff.  Denice
