Fire-King was originally produced in the 1940s for everyday use, rather than display. It was often sold in bags of flour as a promotional item or was given away at gas stations. Fire-King could also be purchased at local grocery and hardware stores. Several varieties of Fire-King dishes were made; nesting bowls, dessert bowls, glass beverage containers, casserole dishes, mugs and more. The vintage nesting bowls, produced by the Anchor Hocking Company, are one of the most sought after collectible dishes of this type.
This mug is from the 1960s, and was probably made to promote the popular TV series. A note on care – Fire-King was not designed for the dishwasher. The extreme heat and harsh cleaning detergent will dull the luster and damage the paint decorations. Hand wash people!
