Q: My wife and I own a 20-inch-high kerosene lamp. The globe and mantle are made of glass, and the base is brass, copper and pewter. The handles are pewter dragons, and the base is decorated with fanciful pewter birds. The lamp is stamped, “Consolidated, Pat. Sept. 990 Apr 30 05 April 11 93.” Value?

A: The stamp indicates that your lamp was made by Consolidated Lamp and Glass Co. of Fostoria, Ohio. The company resulted from a merger of Wallace and McAfee Co. of Pittsburgh and Fostoria Shade and Lamp Co. of Fostoria. Consolidated had a reputation for making fine lamps and other lighting products. The company moved its operations to Coraopolis, Pa., after a fire badly damaged the Ohio factory. Collectors are particularly interested in Consolidated glass made after 1925, when its designers moved towards Art Deco and Lalique-inspired designs. The company temporarily closed during the Depression and closed for good in 1964. A matching pair of old Consolidated molded glass kerosene lamps recently sold for $110 at auction.
