#LeadSafe: Vintage “Crown Corning” White Ceramic Plate, Made in Japan
This vintage made in Japan “Crown Corning” brand white ceramic plate tested positive for lead when tested with an XRF instrument at 46 ppm lead. Tested in 2014. Year of manufacture unknown.
In 2018 the amount of lead that is considered toxic in a modern/newly manufactured item intended for children is 90 ppm lead (or higher) in the coating or 100 ppm (or higher) in the substrate. Dishware is not regulated for total lead content as detected by an XRF. The amount of lead in this plate is considered safe by all standards.
