Corelle®
| Does CORELLE® contain lead? |
| All CORELLE® stoneware products and glazes are made of clay-based materials and glazes used throughout the industry. Decorations, if present, are made from low-lead enamels and fired at temperatures exceeding 1000 degrees F, which binds any heavy metals both physically and chemically so that their release is minimized. The current limit for presence of leachable lead in order to satisfy certain requirements is no more than 0.100 ppm (1 tenth of one part per million) when obtained under test conditions. At no time have World Kitchens results exceeded those which are permissible under the guidelines mentioned above (which are believed to be the most stringent in the world). Also note that tests for the presence of heavy metals are conducted for World Kitchen by internationally certified, third-party laboratories under strict conditions, by trained technicians, and using atomic absorption spectrophotometry analysis following carefully monitored preparation. These steps are necessary to minimize any possibility of contamination or false reading during preparation, testing or analysis. |
