Corning Ware 1-1/2 quart casseroles from Corning Glass's promotional series for Shell Oil from 1971 to 1973, called Blue Macrame. This is the original Corning Ware Pyroceram glass and ceramic material that can go from freezer to oven to table top. The casserole has the code P-1-1/2-B stamped on the bottom.
This early generation casserole is in great shape with no chips or cracks and light wear. This is perfect for us on the stove top burner, in the gas or electric oven, and even the microwave oven.
