Small newer Le Creuset ceramic pot (custard cup?): Both outside and inside tested positive for lead in the 118 to 131 ppm range ppm. The red outside also tested positive for arsenic at 67 ppm.
(Lollipop included to show size.) Newer (exact age unknown).
This item (since it was newer & manufactured by a major brand) was likely leach tested to determine safety. This level of lead and arsenic is more likely a contaminant and not an additive in the manufacturing process.
