I like Corning, Pyrex and Corelle but I cannot give them a 100% Made In USA stamp of approval as some of the products under these name brands are imported from yes, China. I emailed World Kitchen, LLC asking where Corelle and other products were manufactured and this is the answer I received. (See email below.)
Shop wise. Shop USA.

Thank you for contacting World Kitchen, LLC
Most of our Corelle dinnerware is made in the USA. All of the plates and bowls from the Livingware, Lifestyles, Impressions, Ultra and Corelle Square collections are made in the states. The mugs and glasses in our sets are made in China. Also, our Corelle Hearthstone dinnerware collection is made in China also. Pyrex glassware is made in the USA as well. Pyrex metal bakeware is manufactured abroad. Corningware, Revere, Bakers Secret, Chicago Cutlery, EKCO, Magnalite and Visions cookware lines are all manufactured outside of the USA. We hope this information is helpful.
