Following up on my earlier posts , here isexample of XRF test results for a Corning Visions piece. [Year of manufacture: 2018.] I am posting a total of FOUR of these that each look very similar but are different distinct lids that were tested (in three different sizes.)

This piece is a medium saucepan or pot lid (about 8.5 inches in diameter), with decorative radiating ridges around the center of the lid under the top-knob. There are NO brand or model markings on this piece. It was purchased new in March of 2018.

Here are the XRF readings for the specific piece pictured here. These readings represent a 90-second test:

Lead (Pb): 222 +/- 13 ppm

Cadmium (Cd): Non-Detect*

Arsenic (As): Non-Detect

Mercury (Hg): Non-Detect

Barium (Ba): 142 +/- 29 ppm

Iron (Fe): 1,524 +/- 128 ppm

Vanadium (V): 688 +/- 47 ppm

Titanium (Ti): 1,081 +/- 79 ppm

Indium (In): 14 +/- 6 ppm

Magnesium (Mn): 2,635 +/- 216 ppm

*Non-Detect = negative within the testing limitations of an XRF instrument.

While this particular piece of Visionware was positive for (low levels of) lead, some of the Visions pieces I have tested over the years have also been completely lead-free (“Non-Detect” when tested with an XRF instrument.)

In the absence of any reliable method for the consumer to be able to distinguish between potentially leaded and potentially lead-free items, I personally do not use Corning/Corelle Visionware for my family, nor do I recommend this line of products at this point. Instead, I choose undecorated clear glass (new Pyrex is generally good), quality stainless steel, or (un-enameled / undecorated) cast iron for cooking.

That said, just because a piece is positive for lead using XRF technology does not mean the lead is necessarily leaching into your food (now or in the future), however because lead-free options are available I always make lead-free choices for my family.

Thank you for taking the time to read this post and also for sharing it with others!

As always, please let me know if you have any questions! [Most questions you might have related to Corning Visions are answered on this piece here.]
