Silver Bordered Vintage China Mug / Tea Cup: 104,700 ppm Lead [90 ppm Lead is unsafe for kids.]
Mug with “silver” border (where your lips would go!) It turns out the “silver” is achieved by using Leaded glaze! Inside of cup is 845 ppm lead, “silver” border is 104,700 ppm Lead. Tested with an XRF instrument in 2014. I apologize that I did not capture information about the maker or pattern on this…
