Plain White Milk Glass (Bottom) of Larger Mixing Bowlįor context: the amount of lead that is considered toxic for a child in a modern toy (in the paint or coating) is anything 90 ppm lead or higher. Here’s the breakdown of XRF levels for this pattern… White Floral Pattern of Larger Mixing Bowl To learn more about XRF testing, Click HERE.Īs you can see from the second picture (above), the leaded coating does wear off over time… and where do the little bits go? Where does the chipped or worn off material go when you nest the bowls? Where do the bits go when you wash the bowls? Do you wash the bowls when you take them off the shelf (after they have been put away stacked/ nested?) I doubt it.įor #SaferChoices for mixing bowls, please check out this post. If you can find the same values (for total XRF detectible lead content) on similar bowls and pieces with the same pattern, then it is a pretty solid educated guess that all of the pieces with this pattern will have similar lead levels. As with any scientific process, being able to replicate results is very important. What I think is excellent is that these readings are very close to the readings I got when I tested a similar item from this pattern years ago. When I first posted about this about 5 years ago I was shocked at how high lead these were (when tested with an XRF instrument), and later I was shocked again to find out that they also tested positive with a LeadCheck swab. This pattern was the pattern that started it all for me, in terms of finding incredibly high lead in vintage pyrex. I’m super excited to now own a set of these incredibly lead-toxic mixing bowls for my “museum of lead” collection!
