Callie Beller Diesel Posted August 1, 2022 Report Share Posted August 1, 2022 It’s important to note the difference between durable and toxic too. Before looking at the possible toxicity of the compounds leaching out, the fact that the dishes are being corroded by the comparatively weak acids in lemon means they’re not durable. Even if the glaze contains nothing that’s going to do any harm, if the flux balance and silica:alumina ratios are off, the glaze can still break down or be too soft for practicality in functional ware. Not enough people take into account that using too much of some of the ingredients that people have concerns about is just straight up impractical. Or expensive. Or wasteful. Double digit percentages of barium carb in a glaze is just overkill for colour response, and barium mattes are stupid soft and easily scratched. When you had the breakage tested, if the results came back non-toxic, it could just mean that however much of whatever was coming out of them might not have been enough to hurt you. Or it could be that whatever came out of them wasn’t on the list of things that would have been regulated for dinnerware in 1989. It’s a short list in North America: only cadmium and lead are on it as of this writing. Min 1 Quote Link to comment Share on other sites More sharing options...
Babs Posted August 1, 2022 Report Share Posted August 1, 2022 Stick a bit of broken pot in the dishwater for a while, see if it likes that. Any matte glazed dinnerware makes my hair and teeth stand on end when cutlery scraped them. Not durable in most cases Quote Link to comment Share on other sites More sharing options...
