Our specifications are that stoneware products and glazes are made of clay-based materials and glazes used throughout the industry.

Please note that to satisfy requirements concerning consumer warnings on packaging at time of sale and/or advertisement in the state of California (so-called California Proposition 65), only traces of heavy metals (including lead) are permitted. The current limit for presence of leachable lead in order to satisfy California requirements is no more than 0.100 ppm (1 tenth of one part per million) when obtained under test conditions. At no time have our 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.

These are ground up mixed, in specific quantities, with water. The resulting slurry is sprayed onto the pot (or the pot is dipped in it) and it is fired in the kiln at or around 1200-1600 degrees. It all melts together on the outside of the pot and basically turns into a type of glass. The FDA specifies allowable amounts of lead, cadmium and other substances. All of the glazes that we use meet or exceed FDA requirements.
