When tested with an XRF instrument this mug came in with the following readings:
How much Lead is “too much” Lead?
The amount of Lead that is considered unsafe – and illegal – in a modern / newly-manufactured item made and sold for use by children today is anything 90 ppm Lead or higher in the paint / glaze or coating, and anything 100 ppm Lead or higher in the substrate. Ceramic dishes (including mugs) are not covered by this regulatory standard (even though it is my opinion that they should be — because children obviously use dishes!)
If this mug was manufactured today with these levels and (explicitly) sold as “intended for use by children” it would likely be considered both unsafe and illegal. If it were manufactured today and sold for use by adults (i.e. not explicitly marketed as “intended for use by children“), it would be considered perfectly safe and legal (as long as it met regulatory limits for leach testing of Lead – at the time of manufacture)!
Note: I have learned that leach-testing conducted by manufacturers is generally not inclusive of the exterior surfaces of a vessel used for cooking or consuming foods, so it is unlikely that the exterior of these mugs complied with the leach testing standards that were in place when it was manufactured.
