The Imperial Glass Company was organized in 1901 in Bellaire, Ohio, and started manufacturing glassware in 1904. Their early products were jelly glasses, hotel tumblers, etc., but by 1910 they were making a name for themselves by pressing quantities of carnival glass that was so popular at that time. In 1914 NuCut was introduced to imitate cut glass. In 1936 Interial introduced the Candlewick line, for which it is best known. In 1951, a major ad campaign was launched, making Imperial one of the leading milk glass manufacturers. In 1940 Imperial bought the molds and assets of the Central Glass Works of Wheeling, West Virginia; acquired the molds of Heisey glass in 1958, and in 1960 the molds of the Cambridge Glass Company of Cambridge, Ohio. Imperial used these molds, and after 1951 they marked their glasswre with an "I" superimposed over the "G" trademark.
