Test on exterior red writing:
- Cadmium (Cd): 396 +/- 29 ppm
- Selenium (Se): 79 +/- 46 ppm
- Zinc (Zn): 17,300 +/- 800 ppm
- Iron (Fe): 1,431 +/- 287 ppm
- Chromium (Cr): 1,682 +/- 177 ppm
- Titanium (Ti): 2,822 +/- 284 ppm
Test on plain clear glass – on bottom exterior of cup:
- Cadmium (Cd): 18 +/- 10 ppm
- Titanium (Ti): 169 +/- 70 ppm
- Palladium (Pd): 9 +/- 6 ppm
- The Cadmium in this test may be from trace micro dust contaminating the surface as a result of deterioration of the red writing on other parts of the glass.

Hi Tamara, Can a PLAIN glass mug with no writing or image of any sort contain lead or other unsafe metals? Can a stainless steel with no writing or image of any sort contain lead or other unsafe metals? I would be so very grateful if you could send me a response to my email. Thank you very much for your time and the work that you do.
How can you tell if your measuring cups with red writing are vintage or not, short of replacing everything you own?
If you look at each of the posts on measuring cups (click the “measuring cup” keyword at the top of the post) there is some guidance in several of the posts.
