amberina glass

amberina glass, blended colour glass in which the lower part, a yellowish amber, merges into a ruby-red colour higher in the vessel. It was patented in 1883 for the New England Glass Company at East Cambridge, Mass., and was produced extensively there and by the successor company, the Libbey Glass Company at Toledo, Ohio, into the 1890s. The base metal was an amber glass containing some gold, and the tinges were developed by applied reheating. The glass was sometimes blown in molds. A wide range of table and ornamental wares, with diamond or ogival designs, or swirled ribbing, were produced by the New England Glass Company, and amberina glass was also produced at New Bedford, Mass., under the name rose amber.
