Set of 4 Vintage Caloric by Raytheon Gas Range Stove Steel Grates Set. Each measures 8 1/4" x 8 5/8", each sits 1 5/16" high. Will fit other model stoves. These came from a 1974 era Caloric gas stove that my parents bought new. Good condition with normal aged patina - see the detailed photos. 

Caloric Corporation began as the Klein Stove Company in Philadelphia in 1890. The Caloric brand was introduced in 1903. It was reorganized in 1946 as the Caloric Stove Company in Topton, Pennsylvania. The company was renamed Caloric Appliance Corp. in 1954 and became famous for offering a complete package of kitchen appliances in the 1950s and 1960s. Its most popular product was their built-in wall oven. In 1967, it was acquired by Raytheon Corporation which also owned Amana refrigerators and Speed Queen laundry products. By the early 1990s, Caloric was absorbed into Amana and the Caloric brand was phased out. The Topton plant was shut down in 1991. In 1997 the company was purchased by Goodman Global, a heating-and-cooling manufacturer who sold it to Maytag (now part of Whirlpool) in 2002.
One important feature of the Caloric gas stove in the 1960s was the infrared burner, which cooks through radiant heat. This distinguished Caloric ovens from their competitors, which produced gas ovens comprising two burners: one positioned lower for baking and another positioned on top for broiling.
