- Cobalt (Co): 1,973 +/- 257 ppm
Test focused on area of dish with only plain white glaze:
- Lead (Pb): 67 +/- 28 ppm
- Barium (Ba): 2,151 +/- 178 ppm
- Zinc (Zn): 40,000 +/- 94 ppm
- Copper (Cu): 638 +/- 94 ppm

I have square bowls that were sold in a very similar line , corelle stoneware. It is a dark hunter green inside and matte black on the outside. All of the matching plates broke but the bowls survived my Childrens careless dishwasher chores. Have you tested any of the other stoneware lines?
