The Consolidated Lamp and Glass Company was formed in Fostoria, Ohio in 1893 from the merger of the Fostoria Shade and Lamp Company with Wallace and McAffee Company. They moved to Coraopolis, Pennsylvania when their glassworks burned down in 1895. In the 1890′s they produced some art glass vases and bowls, but for many years their main production was high quality lamps, globes and shades. Beginning in 1925 its chief art glass designer was Reuben Haley, who designed a number of famous lines of art glass, including “Martele” (“hand wrought”) in 1926, inspired by the work of Rene Lalique (it featured floral and bird designs and nude motifs), the “Catalonian” line in 1927, a reproduction of old glass from the Spanish province of Catalonia, and, in 1928, the Ruba Rombic line of Art Deco inspired wares. They also produced a line of acid etched designs called Florentine glass.

The Consolidated Glass works was shuttered from 1932 to 1936 by the Great Depression. Many of their molds, technically owned by the heirs of Reuben Haley (who died in 1933) were transfered to the Phoenix Glass Co. so production, particularly of the Martele line, could continiue. These molds were reclaimed in 1936 when Consolidation production resumed. In the 1940′s and 1950′s they continued to produce art glass; however, much of it was their milk glass line called “Con Cora.” The factory was destroyed by a fire in 1963.
