Teacup: 47,200 ppm Lead (Pb).
Fine Bone China
For Context: in 2018 the amount of lead that is considered toxic in a modern/newly manufactured item intended for use children is 90 ppm lead (or higher) in the coating, paint or glaze or 100 ppm (or higher) in the substrate.
Dishware is not considered to be an “item intended for children” (even newly made china and mugs that are manufactured in the United States) and, as such, is not regulated for total lead content as tested/detectable with an XRF instrument. Here’s a recent article about lead in glassware.
So many people think “Made in the USA” or “Made in England” inherently means a product is higher quality or safer. When it comes to Lead (Pb) content in dishware that is a myth. In fact most Made In England vintage china that I have tested has been very high lead.
