<p>[QUOTE=&quot;Melissa Brown, post: 254444, member: 4746&quot;]Thank you for the links [USER=107]@TallCakes[/USER] &amp; [USER=541]@wenna[/USER]! Great information and I&#039;ve requested to join the fb groups. Thanks, exposure over time is the culprit. When I do my decidedly low tech glaze stability tests, I lay a lemon slice on the piece for varying lengths of time. If the citric acid degrades the glaze at all I don&#039;t consider it food safe. It&#039;s not just exposure to the metals and minerals in the glaze, it&#039;s that utinsil marks will show, it will stain, and of course leach any controversial stuff.</p><p><br /></p><p>About eight years ago manganese (interesting to see it mentioned in the article about ABCG!) went on the toxic radar landscape in the pottery community after a well known (very old) potter came down with a neurological disease and died. He worked extensively over decades with manganese. Now it&#039;s another target of fear and distain in the pottery community. I used/use a glaze with it in it extensively, now only on the outside of my pottery where it doesn&#039;t come in long term contact with food. I use a different glaze inside the pots. The public is &quot;safe&quot; but it&#039;s still in its more dangerous dry powdered form in my studio. I take precautions but it&#039;s still around.</p><p><br /></p><p>Like [USER=78]@gregsglass[/USER] said. If we all followed every warning, we wouldn&#039;t do anything. I&#039;d wrap myself in a bubble wrap (which would also turn out to be bad for you) and sit in a corner (uh oh, not enough exercise will kill you!!!). I like to be informed and choose my battles. I use my old crazed dishes, you know they&#039;re risky because bacteria (!!!!!) can harbor in the cracks, eat way too much butter, and use manganese in the studio. Life in the fast lane! Ps: we always called buckshot lead poisoning;-)[/QUOTE]</p><p><br /></p>
