I have some old painted Pyrex bowls. Over time the paint is coming off and I have often wondered if it is lead-based paint. I just did a home lead test that came out POSITIVE for lead. I don't find much on the web about this but I urge caution if you have any of these bowls. I have thrown my away.
Yes, I did the same thing- tested my bowls with a home kit and they turned red (positive ) BUT I called the Pyrex company (got the number from their website)and they assured me that all of their products (even the old ones)were in the safe lead limits set by California standards (which have the toughest standards). I also talked with a lead expert and she did say that those home kits could have false positives. I would love to know why the bowls tested high for lead (the yellow testing liquid turned bright red in the kit and usually the redder it is the higher the lead count). I trust the rep. I talked with on the phone- she had exact numbers and stats so I don't know what is up but I feel better having used those bowls for years!
