OK guys, please don't shoot me for bringing this up again after all the
reams of information recently posted on managanese toxicity.
A friend and I use a high manganese bronze glaze for certain non
functional pieces. However, she recently glazed some cups with it on
the outside with a clear glaze inside. Since the lips would touch the
outside of the lip of the cup where the bronze glaze is, do you believe
there is a potential health problem?? (Monona, are you listening?) I
was very emphatic telling her how deadly manganese dioxide can be. She
said she would not sell the cups until she heard your answer.
Thanks for you help on this and a million thanks to all who have
responded to my questions regarding my new studio and concrete floor,
etc.
