Summary

The effects of soap pad and multiple automatic dishwashing use on lead release are summarized. Determinations were made on commercially available lead glazes which are acceptable by FDA and ISO standards. It was found that with multiple teachings, automatic dishwashings, and intervening scrubbings that the lead-release values were within the allowable limit set by ISO. The amount of lead that was leached out after the intervening scrubbings was less than 1 ppm. It was concluded that if ceramic ware is properly fired and has a good glaze composition, the teachability of lead from that glaze is within the allowable limit stated by the ISO.
