Corningware MACRAME pattern. Highly collectible piece. Like new 8x8.

Pattern: This specific design is known as the "Macrame" pattern, characterized by its striking blue geometric design on a classic white base. Origin: The "Macrame" pattern was never sold in stores; it was exclusively produced as a promotional giveaway by the Shell Oil Company between 1971 and 1973, making these pieces highly collectible. Material and Use: Like other vintage CorningWare, it's made from Pyroceram, a durable glass-ceramic material that can withstand extreme temperature changes, allowing it to be used for cooking, freezing, and serving. #8
