Corning Mug. Year unknown.
Tested with an XRF instrument.
Positive for lead at 33 parts per million (ppm), +/- 13 ppm.
This is considered safe by all standards.
The amount of lead that is considered toxic in a modern/newly manufactured item intended for children is anything 90 ppm lead or higher. 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.

I have these! Glad to see at least one item I already had was at least within safety limits, ha ha ha.
Question? Are green Tupperware canisters safe?
Tamara, I bought 4 of these at the Goodwill today and am so glad they are lead-free. Even though they look to be older by the shape the look just like the one pictured and have Corning USA on the bottom of the. They match my new Corelle Winter white really well. Thank you for showing them on your website.

I bought Sweese mugs on Amazon as they advertised that they were lead free, but now I am wondering if they really are. Do you have any experience with these mugs? Ceramic seems to hold the heat better of coffee than the glass of Anchor Hocking, Pyrex or Libbey.
Because of the very clear information you provided, I was confident in purchasing one of these white, undecorated Corning mugs at Goodwill yesterday. I am going to wash it tonight and begin using it tomorrow. Thank you, Tamara.
