lead-glazed
Toxic lustrous finish
Lead-glazed describes pottery or ceramics coated with a glaze containing lead oxide, which produces a smooth, glossy finish when fired.
This technique dates back thousands of years and creates distinctive colors and shine: lead-glazed earthenware, a lead-glazed tile floor.
Health concerns about lead leaching have largely replaced it with safer alternatives in modern food-contact ceramics.
