Following up on my earlier post, here is another example of XRF test results for a Corning Visions piece. [Year of manufacture unknown.]
This piece is a small saucepan and differs from the piece I posted earlier in that it is “Made in France.” It also has the 3-D diamond/pyramid shaped pattern on the bottom of the pan. These ridges can be felt on the inside surface of the pan. The bottom surface of the pan is flat.
This piece purchased at a Portland, Oregon Goodwill store in the summer of 2018 for $2.99.
The markings on this piece (on the handle) are:
- VISION
- CORNING
- FRANCE
And on the back of the handle (the underside) in backwards print (so they can be read correctly when viewing them through the clear amber glass of the handle):
- A B

Here are the XRF readings for the specific piece pictured here:
- Lead (Pb): Non-Detect*
- Cadmium (Cd): Non-Detect
- Arsenic (As): Non-Detect
- Mercury (Hg): Non-Detect
- Barium (Ba): 4,289 +/- 241 ppm
- Bromine (Br): 231 +/- 21 ppm
- Zinc (Zn): 10,500 +/- 400 ppm
- Copper (Cu): 170 +/- 60 ppm
- Iron (Fe): 834 +/- 219 ppm
- Vanadium (V): 1,151 +/- 132 ppm
- Titanium (Ti): 14,700 +/- 800 ppm
- Zirconium (Zr): 15,600 +/- 600 ppm
- Platinum (Pt): 305 +/- 110 ppm
*Non-Detect = negative within the testing limitations of an XRF instrument.

While this particular piece of Visionware is lead-free, some of the Visions pieces I have tested over the years have been positive for trace (very low) levels of lead. As a result, I personally do not use Corning Visionware for my family, instead I choose undecorated cast iron, clear glass and stainless steel for cooking.

similar to items I use for my family, click here.
Thank you for taking the time to read this post and also to share 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.]

Tamara – can you recommend brands of stainless steel and glass pots and pans to purchase?

Have you tested visionware made in USA?
Why do you use Stainless steel? Isn’t most of it recycled with trace levels of RADIOACTIVE ☢️ elements? What about nickel leaching? Is this something to worry about (read a paper that it does’t leach all that much after the 6th use, but is this leaching amount still hurtful? I,m asking mainly for 18/10 SS.
What about iron cast? Iron is the MOST OXIDANT metal in the body! You can have excess iron in your bodies (as the majority of the population does) and still be anemic (which is often an argument for iron). What do you think of my comments?
Do we know anything about whether this barium is ok? I am guessing none of it leaches but I don’t know much about barium or barium oxide which is supposedly an ingredient in this glassware.
For me I have concerns because it seems to not be well studied in terms of potential impacts.

Hi Tamara, I live in London and it’s been five months since I bought a Vision saucepan because I wanted to choose a healthier alternative for cooking. A week ago I found a tiny hole in the inside of the saucepan, the size of the tip of a toothpick. I always clean the saucepan with great care not to scratch it and I have not used any utensil that could have created that hole. My question is whether this can cause any material from the saucepan to be released into the food or cooking water?
Thank you!
Sheila.
I still have a question about the barium element detected in the Visions Bar (Ba) pot: 4289 +/- 241 ppm. Is it harmful to humans?
I have a brown glass round baking dish with matching lid (not ridged as your other examples) stamped pyrex and later at the bottom also says Corning. Says USA. My mom believes she purchased these in the 1980s. Is that “vintage” and should I be worried? I thought glass was almost always safe but what makes it brown tinted?
I’ve scoured your posts and web pages and have yet to see a clear glass saucepan recommendation. I’m guessing this is because you’ve never found one, but IF YOU HAVE … could you please provide a name and/or link? Thanks!
