Have you tested any of the other dishes in this collection? Dinner or lunch plates? Would they have the same composition?
Yes I have this Corelle collection, is the plate and bowl sage also?
Have you ever tested Corelle Splendor, Kyoto Leaves or Linen Wave? I am trying to get one of the recent models and I don’t know if they are safe. Thank you very much for all the info that you are giving us. You are amazing! Ani Onofrei
Hi- thanks for your work! Do you think it’s safe to assume there is no cadmium/lead/etc. in the entire Corelle Portfino collection, including CorningWare Portfino baking dishes? Thanks so much.
The baking dishes are a different substrate possibly and therefore possibly a different makeup of the glaze and I have not tested them. I would only extrapolate these results to the glass plates in the pattern – and other products made of the same white glass substrate material – which would therefore likely have similar paint / glaze / designs / coating.
Thank you for testing these, Tamara! I have some plates in this design and would love to get more. I’m so happy to learn that they are free of Lead, Cadmium, Arsenic, Mercury and Antimony. But I don’t know if the other metals (barium, zinc, iron, chromium, vanadium, titanium or cobalt) you listed, or the quantities you recorded, are safe for dishes. Would you consider these dishes safe or not?
So long story short are these safe to use despite the things that are found in it? I just ordered a set and they get hot in the microwave. I used to think that was a sign of lead. No? Thank you!
They are safe by all standards. Hot in the microwave is not a sign of Lead. Thanks for commenting!

I just bought an entire set of these: bowls, dinner, salad and bread plates. If I understand correctly these are safe, correct?
My question is: how do we know the plates are pre/post 2005? My mom bought us the Corelle Country Cottage pattern at Walmart in 2019. But would that mean that it’s safe? I wonder how long it could have been sitting in the shelf for.
