I have their meat marinator, red bottom and white top. 40 years and still BBQing! For food storage, we use the cheaper plastic containers from HEB. I don't mind sending those out the door with visitors! Definitely do not use in microwave. We also just use zip lock baggies for some. Easy to share with my brother, or toss if too old.
My CorningWare is the French white. Love it! But not collectable. Yet...
