Pyrex sold its famous white tempered glass opal ware from the mid-1940s to 1986. They had the popular consumer line as well as a commercial line for restaurants. I have mixing bowls and casseroles from the consumer line and plates, saucers, and cups from their commercial line.
You'll also find some of the traditional vintage Corelle patterns, such as Butterfly Gold, Spring Blossom Green, and Snowflake Blue, as well as the less common, but still nifty Wildflower and Spring Meadow. Only vintage patterns!
