Hmmmm. Very interesting. I'm just seeing this now for the first time.

I'm in Europe... I think most of our tempered glassware is original Pyrex, but I'm going to have to check if anything new has been bought in the past few years. We don't bake much these days, and the baking dishes are certainly from the US anyay, but not so sure about the measuring cups we use to microwave things sometimes.... yikes.

(There is a LOT of Chinese counterfeit stuff in circulation here!)

Lara, I'm sure anything you have that's truly made by Corelle is fine. If a product does not have their seal, or if its origins are somehow suspect, then you might worry. The problem we see is with products (any sort) which bear "original" brand names which have been faked. It can be hard to tell the fakes from the imitations, and the price isn't always telling.
