When using an XRF instrument to test the cup pictured here (which is made of solid red plastic with no painted markings or decorations) it had the following readings:
- Barium (Ba): 162 +/- 90 ppm
- Zinc (Zn): 66 +/- 8 ppm
- Copper (Cu): 23 +/- 13 ppm
- Iron (Fe): 41 +/- 17 ppm
- Titanium (Ti): 835 +/- 229 ppm
All test results reported on this blog are replicable, science-based and accurate. The test result set above was for a test of the item pictured for a full 60 seconds (one minute) in “Consumer Goods” mode. If a metal is not listed above, it was not detected by the XRF instrument in this mode when testing the item pictured here.
A word of caution, given it is nearly impossible to tell the exact year of manufacture of a Tupperware product, the fact that this red cup is negative for Lead, Cadmium, Mercury and Arsenic does not mean that all other red Tupperware items will also be negative. More testing and research is necessary to make that determination. That said, all dark red Tupperware items I have tested to date (about 10 items so far) have been negative for the five primary heavy metals that I look for in my work (Lead, Cadmium, Antimony, Arsenic and Mercury.)
If you have any information that could help date this particular cup that would be very much appreciated. Thank you for supporting this work in this way.
If you appreciate this work and would like to see more test results like this, please consider contributing to the GoFundMe for my advocacy work: http://www.GoFundMe.com/LeadSafeMama. I do “take requests” as I live near quite a few antique stores and could easily go purchase something that you might want tested if the cost of the item were covered and a contribution that also helped with the cost of testing was made. Please e-mail me if you are interested in having me purchase something specific to test (and are in a position to help cover the cost.)
As always, thank you for reading and for sharing my posts.
Please let me know if you have any questions.
