Does this coffee mug test positive for Lead? NOPE!
When tested with an XRF instrument, this blue glazed Bennington Potters mug (made in Bennington, Vermont and purchased online directly from the manufacturer in 2019) was ACTUALLY LEAD-FREE! AMAZING!! Each test was done for a minimum of 60 seconds, using a freshly-calibrated XRF instrument, testing in Consumer Goods mode. Test are repeated multiple times to confirm the levels. Test results are accurate, science-based, and replicable.
I am so excited to have found an honest-to-goodness Lead-free mug – that is AMERICAN MADE, too! I am a little sad that it is so expensive ($22 + $9 shipping), but given how consistently newly-manufactured mugs still keep testing positive for Lead and other toxicants [often even at high levels!] I really do think it is worth the price – and I also think it is a GREAT GIFT.
Is everything from this company Lead-free?
I have no idea if everything from this company will test similarly to this mug. This is the only example from Bennington Potters that I have tested so far. However, as an educated guess, I would speculate that given how “clean” this one particular mug (pictured here) tested, it is very likely that other products from this company are also Lead-free (as advertised).
Perhaps the most exciting thing is that both the the glaze on this one example is Lead-free, and the SUBSTRATE (the base white clay) is Lead-free as well. With most of the hand-made pieces I have tested (from small potteries that claim their products are 100% Lead-free) the GLAZE is often Lead-free, but the SUBSTRATE is often not Lead-free. The full XRF test results for this blue glazed mug are below.
This is a very large mug (it easily holds about 20 ounces!)- so if that is what you have been looking for (a big mug for daily use for coffee, tea or soup), I think it is an excellent choice!
Do you want to help me collect some more data points for this company?
I would love to test some more products from this company to determine if they are Lead-free across the board. I really want to have an American pottery company that I can confidently recommend to families who are looking for safer choices that are also heirloom quality. I will share this post with Bennington Potters and see if they might send me a few different examples to test and add to the blog.
In the meantime If someone wants to send me a gift of some other examples (other colors and designs of mugs from this company) to test and report on on the blog, I would love that 😉 – As my regular readers know, I like to have several data points before venturing a recommendation that any item, brand or product line seems a good bet to be “likely consistently Lead-free.”
Since the cost of purchasing one of these mugs is comparable to what I ask for as a contribution for testing and reporting an item on the blog – I hereby offer that I will test any additional Bennington Potters mugs that are sent to me and post them to the blog without charge – and just hold on to them afterwards for my family – or to give them away as prizes or gifts to others (assuming they will very likely be Lead-free)! 😉

As always, thank you for reading and for sharing my posts. The testing I do (and the results I report here on my blog) is fully directed by my readers… I test what you send me for testing. If you are interested in sending me a single item for testing, click here.
Please let me know if you have any questions.
