XRF Test Results For Zack 20085 Rezzo Stainless Steel Tumbler

 Zack 20085 Rezzo Tumbler
Heavy Duty Stainless Steel

This item consists of one “component” with two distinct areas needing testing:

1. The main body of the cup.
2. The logo area of the cup (which may be etched or may be painted).

As I would have anticipated with an item like this (newly manufactured stainless steel) it is negative for Lead (Pb), Cadmium (Cd), Arsenic (As), and Mercury (Hg). Generally, the only concern sometimes for stainless items (that are one contiguous piece of metal) can be if the logo or design might be painted with lead paint. This was not the case for this item.

Below are the full XRF readings for each area in this item (when tested using “Consumer Goods” mode). For each of the areas tested multiple tests were done to confirm the levels (for 30 seconds or one minute per test). For any element/metal detected, levels below 90 ppm are generally considered “trace” and not an additive to the product.:

• Chromium (Cr): 181,800 +/- 1,600 ppm [18.1 %]
• Tin (Sn): 208 +/- 55 ppm
• Copper (Cu):  2,270 +/- 453 ppm
• Nickel (Ni): 80,700 +/- 1,600 ppm [8%]
• Iron (Fe): 717,300 +/- 2,700 ppm [71.7%]
• Vanadium (V): 1,061 +/- 444 ppm
• Cobalt (Co): 3,149 +/- 1438 ppm
• Magnesium (Mn): 11,600 +/- 1,200 ppm [1.16%]
• Lead (Pb): Non-Detect (ND)/Negative
• Arsenic (As): Non-Detect (ND)/Negative
• Cadmium (Cd): Non-Detect (ND)/Negative
• Mercury (Hg): Non-Detect (ND)/Negative

Logo Area on Cup
see image below

Note: Since the readings for the logo are essentially the same – or close to the same within the margin of error (and in the same proportions) as the part of the cup without the logo, it would appear that the logo is not painted on the cup but etched.

• Chromium (Cr): 154,400 +/- 2,900 ppm [15.4%]
• Tin (Sn): 250 +/- 61 ppm
• Copper (Cu): 2,331 +/- 475 ppm
• Nickel (Ni): 86,600 +/- 1,800 ppm [8.6%]
• Iron (Fe): 737,100 +/- 3,100 ppm [73.7 %]
• Cobalt (Co): 3,419 +/- 1,453 ppm
• Magnesium (Mn):  13,700 +/- 1,300 ppm [1.37%]
• Lead (Pb): Non-Detect (ND)/Negative
• Arsenic (As): Non-Detect (ND)/Negative
• Cadmium (Cd): Non-Detect (ND)/Negative
• Mercury (Hg): Non-Detect (ND)/Negative

NOTE: XRF testing is recognized by the Consumer Product Safety Commission as an acceptable and accurate way to screen consumer goods for potential toxicants. The Niton XL3T model that I use tests down to single digit parts per million for any metals detected. I am not a lab (and do not represent a lab or work with a lab) and, as such, no formal reports (other than the results as shared in these blog posts) are created through my work. That said the results are accurate (within the limitations of the testing methodology) and fully replicable by others using the same instrumentation (and also generally by others using digestive or destructive testing as long as the components are tested separately.)

Thank you for reading my posts and for sharing!

As always, please let me know if you have any questions.
