Newer (2017) Stumptown Coffee Roasters Enameled Metal Mug.
Tested with an XRF instrument. Positive for Lead at 5,192 ppm.
The amount of lead that is considered toxic in a modern/newly manufactured item intended for children is anything 90 ppm Lead or higher in the paint or coating.
Mugs are not considered items intended for use by children and, as such, are not regulated for total lead content as detectable when tested with an XRF instrument.
While enamel is considered inert (by some in the cookware industry) I do have concerns that something specifically intended for holding a highly acidic beverage (coffee) has so much Lead, especially given it is intended to be used (and will likely be used) on a daily basis for said acidic beverage.
Regardless of whether the product passed leach testing at the time of manufacture, there is a concern for what might be possible (in terms of leaching) with deterioration and heavy use of the product (and wear of the finish.) This is my concern for all enamelware.
