Pottery and Ceramics Glaze (Lead, Silica Dust, Kiln Fumes) — household safety profile
Elevated riskPottery and ceramics involving three exposure pathways: silica dust from clay handling/mixing (silicosis risk), lead in some glazes (especially imported and vintage), and kiln fumes (CO, SO2, metal fumes during firing).
What is this product?
Pottery and ceramics involving three exposure pathways: silica dust from clay handling/mixing (silicosis risk), lead in some glazes (especially imported and vintage), and kiln fumes (CO, SO2, metal fumes during firing). Lead-glazed ware used for food: lead leaches into acidic food. FDA limits: 0.5 ppm lead for flatware, 2.0 ppm for small hollowware. Vintage and imported pottery frequently exceeds FDA lead limits. Lead-free glazes are standard in professional ceramic supply but hobbyist/imported glazes may contain lead.
