How worn is your vintage Pyrex? Even with very worn paint, this piece is still positive for a high level of Lead (Pb) at 23,000 ppm.

Above is a reddish orange vintage Pyrex refrigerator dish with most of the paint worn off.

When tested with an XRF instrument, this piece had the following reading for Lead:

Lead (Pb): 23,000 ppm.

This is a great example of how the colors on these pieces wear. The question is… where does that Leaded color go? Also an important note: Even with so much wear, it still tested incredibly high for Lead.

What do you think the Lead level may have been with the color fully intact?
