Ceramic Baum “Pyramid” design mug: 26 +/- 15 ppm lead.
The interior was negative/ “non-detect” for lead (Pb). Both the interior and exterior were also non-detect for cadmium (Cd), arsenic (As), and mercury (Hg.) Tested with an XRF instrument.
The amount of lead that is considered toxic in an item for children is anything 90 ppm or higher. The level of lead in this cup is well within the safe range by all standards (American and European.)
