So is the cherish butter dish safe?
Hi Julie,
Yes. But it still has Lead, so I would not have it in my home (from a philosophical perspective). It is safe as far as being “Lead-safe” for sure. It’s a good choice generally.
Tamara
Thank you. I just bought the Cherish Corelle dishes thinking they were safe. Do you know about the plates, bowls? After following you, I thought these would be okay as they are white, new. The Corelli you recommended, I could no longer buy. Sorry to bother you. Thanks again for all you do.
Hi Julie,
The Cherish Corelle dishes are NOT ceramic they are GLASS. They should be Lead-free. These extra pieces to the set are not glass they are CERAMIC and, like the mugs – can test positive for low levels of Lead.
Tamara
Julie, the dishes are lead free, Tamara has tested them for me. The ceramic mugs in the set tested at around 60 ppm though (safe by all standards) but we chose to get read of in lieu of Libbey robusta clear glass mugs.
Thank you so much. Do you have mugs in your Amazon store? Next I have two pieces of China I would like tested? Do you have time? Cost? I would not need them back. I do appreciate all you do. So thankful for you.
Hi Julie! There are quite a few posts here with Lead Free mug choices. Check out the following links:

Hi again Julie,
For the second part of your question (testing dishes): https://tamararubin.com/2019/08/tamara-can-i-send-you-one-of-my-dishes-to-test-for-lead/
Tamara
Thank you, Tamara. I am the one who sent it. What a disappointment, could you throw it away then? No reason to spend time on sending back something that has lead. I purchased it on the Correlle’s website: https://www.corelle.com/product/cherish-butter-dish.
Thank you once again!

Hi E.!
Thank you for your patience with my timeline for reporting these thing! Are you sure you don’t want to keep it? It is *almost* Lead-free! The food surface is Lead-free. I think the Lead also might be under a clear coat at the bottom (the black glaze of the logo appears to be under a clear coat.) Let me know (maybe think about it until the morning!)
Tamara
Plus I did not realize it was Corelle… but that makes sense. The new Corelle CERAMIC pieces consistently test positive for a very low level of Lead (in logos and sometimes in the base ceramics.)
Tamara
Hi Ekaterina,
Here’s the other piece (also has trace Lead – in all components): https://tamararubin.com/2021/01/world-kitchen-cherish-pattern-white-ceramic-gravy-boat-with-lid-30-ppm-lead-on-the-food-surface-safe-by-all-standards/
Let me know by tomorrow what you definitely want me to do (send an email or whatever!)
Tamara
Oh Ekaterina!
