While I don’t know the exact year of manufacture for this Corning mug with a floral pattern on the side, there is an “81” on the bottom and it has a color scheme that is also consistent with things like this from the early 1980s. The decorative element on this Corning mug tests positive for lead at 15,500 ppm, which is similar to another Corning product I tested (link here). As a modern conservative reference standard, the amount of lead that is now considered unsafe in an item manufactured as “intended for children” is 90 ppm or higher. Here in the U.S. dishware has never been regulated for total lead content nor lead content in decorative elements. Additionally, vintage dishware was not even minimally required to be tested for “leachability” before 1971. A recent study confirmed the presence of and the potential risk of lead in decorative elements in glassware (link here.)

Tamara, did you test the inside of this mug? These were also sold unadorned and Im curious if they are safe.
