Vintage Arcoroc Clear Glass Plate (year unknown), Made in France.
When tested with an XRF instrument the dish pictured here was positive at the following level: 256 ppm Lead. This is common with vintage clear glass (and especially vintage clear glass that was made in France.) New clear glass should be Lead-free.
Here are some links to clear glass choices* for dishes that are likely to be #LeadFree. All of the modern versions of clear glass plates from the following brands that I have tested have been lead-free (each of the links below is to a product from this brand on Amazon):
The amount of Lead considered unsafe in items intended for children is 90 ppm lead or higher in the paint or coating and 100 ppm Lead or higher in the substrate. So the dish pictured here would NOT be considered lead-safe (for use by children.)
Dishes are not sold as “intended for children” so total lead content (as detectible with an XRF) is not regulated (now or historically.) Vintage and antique dishware is also not regulated for total lead content nor lead toxicity.
I am not saying that these dishes (or any specific dishes that test positive for lead) will poison you, I am only saying they may contain an unsafe level of lead by today’s regulatory standards for items intended to be used by children. Lead is one of the most potent neurotoxins known to man and does not belong in our kitchens nor on our dining room table.
