It specifies that the source of the lead is the paint or glaze. I didn't think lead paint was still a thing, but some quick googling is making me a little nervous... It seems quite a few modern mugs contain some amount of lead.

Note it's not just lead, but also cadmium for bright colors. Trendy cookware manufacturer Le Creuset uses cadmium in many of their hues, for example. Many other enameled and ceramic cookware manufacturers do too. Some test results: https://tamararubin.com/2019/02/made-in-france-c-2013-yellow-le-creuset-enameled-sauce-pan-15800-ppm-cadmium-a-known-carcinogen/ https://tamararubin.com/2019/02/made-in-france-c-2013-yellow....

  That’s incredibly frustrating. You shouldn’t need to worry about things like that from a high end manufacturer.

    It's unclear to me whether one should worry, assuming the glaze is intact. The cookware passes California prop 65 standards (extremely stringent). The coloration with the high cadmium levels is not on a surface that contacts food, and even if it was, I don't know that it would leach. But we have no way of knowing without expensive testing! However, even if we ignore the possibility of harm to the end user, I think the author of that blog makes a great point: "By using high levels of Cadmium in manufacturing, Le Creuset has – apparently for decades – been causal in contributing to “the demand for” the mining, refining and manufacturing of a toxic pigment that can (and does) poison others (workers, communities, waterways, the planet) through various processes/at multiple points throughout their manufactured products’ life cycles."

  Did they test how much of it actually ends up in cooked food? Also, those numbers don't tell me much, I want to know how this compares to lethal/toxic dose etc.

  Although to be fair the interior surface is white and came in at ~30pm/150ppm Pb/Cd less than 1/100th compared to the bottom flame surface of the pan. I'd wonder whether modern 2020 Le Creuset has similar numbers to this 2013 pan. It's still not as low as I'd like for a simmering pot/dutch oven, but it is clearly in the decorative outer coating. Also not surprising Cadmium's in bright yellow... lucky it's not Uranium!

    Once upon a time uranium was used to make glass bright green. https://en.wikipedia.org/wiki/Uranium_glass https://en.wikipedia.org/wiki/Uranium_glass

      Uranium oxide was also used quite commonly in a ceramic glaze for bright yellows and reds: https://www.artsy.net/artwork/lucie-rie-lucie-rie-rare-uranium-yellow-glaze-with-bronze-slip-rim https://www.artsy.net/artwork/lucie-rie-lucie-rie-rare-urani...
