Vintage Corning Ware - Anchor Hocking - Blue Bird Friendship Pattern - RARE - Made from Pyroceram, this product was initially used with the space program for its resistance to heat damage and for its durability. This stylish pan is in excellent condition with no chips or cracks and few utensil marks, or signs of overall use. Minimal marking on bottom from sitting on shelf. The Blue Bird Friendship pattern from the mid 1970's is much less common and harder to find than other, more well known patterns, making this pan the perfect addition to your collection.
