My Corning Ware Spice of Life collection all started with the loaf pan on the left. Corning Ware was introduced in September of 1958. The original pattern was white with a blue flowered pattern known as Cornflower. This pattern was produced until 1971. In 1972 Corning Ware launched the Spice of Life (or also known as French Spice) which lasted until 1987.
This collection was found in multiple places including thrift stores and online. The casserole dishes tend to be the easiest ones to find in the the thrift stores, which can go for no more than $4.99 depending upon the size. However, the online retail market will easily sell a casserole dish for $20.00 or more for the smaller dishes.
