Following up on my earlier post, here is another example of XRF test results for a Corning Visions piece. [Year of manufacture: 2018.]
This piece is a small saucepan or pot lid, with decorative radiating ridges around the center of the lid under the top-knob. There are NO brand or model markings on this piece, but it was purchased directly from (and shipped directly from) the manufacturer in the summer of 2018.
Photos of the shipping materials (the packing slip and box with identifying information) are posted below. It is the “Visions V-2.5-C-FL-XP Amb 2.5qt 2.”

Here are the XRF readings for the specific piece pictured here:
- Lead (Pb): 191 +/- 19 ppm
- Cadmium (Cd): Non-Detect*
- Arsenic (As): Non-Detect
- Mercury (Hg): Non-Detect
- Barium (Ba): 90 +/- 45 ppm
- Iron (Fe): 1,480 +/- 195 ppm
- Vanadium (V): 631 +/- 78 ppm
- Titanium (Ti): 822 +/- 106 ppm
- Indium (In): 21 +/- 10 ppm
- Magnesium (Mn): 2,225 +/- 315 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.

similar to items I use for my family, click here.
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.]

More proof (from the packaging) that this was sent directly from the manufacturer (for those who might have any doubts or concerns!)
Hi Tamara… I am loving vintage Visions for stove-top cooking…hoping that the items I got on e-bay are OK… But do you think there is a more reliable safe glass alternative to it?
and thnx for all your research! :-))
Whenever possible I think newly made/ recently manufactured clear glass is a better option. While I expect the Visionware is not likely leaching, I prefer to have my cookware be wholly lead-free.
I’ve never seen any legitimate test showing lead in any piece of Visions cookware itself, which are made of Pyroceram. It’s important to note that the lids are typically Pyrex glass (borosilicate or soda lime) and not made of Visions Pyroceram.
As far as glass or glass-ceramic based cookware goes, I’m not aware of an, overal,l safer cookware choice than Visions or Corning Ware for stovetop use – “safer” intros context also including risk of thermal shock and mechanical durability, as well.
The lid is made in China. I didn’t see any other post from you about the actual Glass vision cooling pot that went with the lid. Is there lead in that?
Thank you!
I just ordered a 5 L visions from Helton tool and home and I wanted to know how I can test that and if you have already (5L)
Thank you so much
