In his book "Anchor Hocking's Fire King & More", Gene Florence says that Sapphire Blue is the most recognized Fire King pattern. These two beautiful individual bakers/custard cups are the thinner, more flared edged bakers1. They measure 4" in diameter, 2" deep, and hold six ounces. They are in unused condition with no chips, cracks, scratches, or flea bites. The bakers are each marked "Fire King".
