Guest JBaymore Posted November 20, 2013 Report Share Posted November 20, 2013 Legally the exact way that lead and cadmium bearing "not food safe" wares are required to be identified is stated in the US by the FDA laws. It requires fired on labeling and even specifies the fonts and size. This is because the pieces can change hands multiple times in their life, and things like verbal instructions, hang tags, and the like go "bye-bye". And unfired writing and stickers fade with time. best, .................john Link to comment Share on other sites More sharing options...

Of course, that leach testing assumes specific firing conditions. I'm curious, though, as to what the legal responsibility of the potter would be if they used a 'food safe' glaze that contained lead or cadmium... and their firing process resulted in higher rates of leaching than seen with the original tests. Would they be 'covered' by the manufacturers claim... or would they bear culpability for not testing the function of the glaze under their personal firing conditions? (Let me emphasize, I'm NOT considering marketing a raku dinnerware line... but I'm intrigued by the legal complexities here...) Link to comment Share on other sites More sharing options...

I addressed this exact issue a bit in another thread recently... that lead to a "blow up" with one forum member....... who apparently felt I was "discouraging" people. Can't remember where it was..... I'll look around and put a link here soon. Short answer..... YOU are responsible. best, ................john Link to comment Share on other sites More sharing options...
