Any additional metals not listed were not detected. As with all posts on this blog, all tests were done with a Niton XL3T XRF instrument in “Consumer Goods” mode, for at least 60 seconds [unless otherwise noted]. Results are science based and replicable.
Is Cadmium a problem?
Note: just because the mug tests POSITIVE for CADMIUM (a known carcinogen / known to cause cancer) that does not mean it is definitely leaching Cadmium. In fact, newer mugs are likely tested for leaching of toxicants (at the time of manufacture).
My big concern is what happens with a mug over it’s entire life span; not whether or not it is leaching just at the time of manufacture, but is it leaching after years of extensive daily heavy use – with acidic and hot beverages (normal, anticipated use for a coffee mug). Leach-testing is only performed – and those results relevant – at the time of manufacture. Mugs have been shown to leach over time with more use as they age (despite the fact that they may not have leached any toxicants when tested at the time of initial manufacture!)
Accordingly, I would personally avoid this mug, would not drink out of it if you offered me coffee in it once — and definitely would not have one in my own home. Hopefully, now that this information is available, “The Talk” might choose to make safer choices for the mugs for their hosts and guests.
To reiterate why I am doing these posts:
While “Toxicants In On-Set Talk-Show Mugs” is obviously an absurdly arcane and limited “consumer product concern”… I thought it might be a fun “conversation-starter”; I wanted to get the attention of talk show hosts on the real issue: the continued widespread use of neurotoxic heavy metals (like Lead and Cadmium) in mass-marketed manufactured consumer goods — so that I could hopefully draw their attention to the fact that, for instance, I have found many newly-manufactured BABY BOTTLES with Lead in them in the past 2+ years, yet – incredibly – no regulatory agency is doing anything about those findings — nor have any recalls been initiated as a result of those findings!
I know the “news cycle” has a short attention span, and there’s undeniably a LOT of crazy and troubling stuff to report on these days, but come on — if LEAD-PAINTED logos and other markings on freakin’ BABY BOTTLES in 2019 isn’t worthy of a few minutes of serious journalistic attention, just what the heck is?!

As always, thank you so much for reading and for sharing my posts.
Please let me know if you have any questions.

Each of the “Set Mugs” in this series was purchased directly from the gift store for the show in question (and based on my research is the official mug for the current 2019 season.)

Glad to see you are still going strong! Do you have a podcast?

Hi Myra! No podcast yet… maybe on the horizon!

I want a coffee mug like the one on today’s show (8-28-20). It has a lid and a handle. Please advise if you will.

Hi Tommie,
My readers direct the things I test by sending me things for testing. I am sorry but I am not accepting new items for testing at this time, but if you subscribe to my newsletter (it’s free) you will be among the first to know when I start testing things again.
