Also called partially colored glass. Dates from 1833 and patented in 1883 for the New England Glass Company of East Cambridge, Mass., and made through the 1890s by its successor, the Libbey Glass Company of Ohio. Manufactured also under the name rose amber in New Bedford, Mass. This blended-color glass is characterized by the lower part of a piece colored a yellowish amber color that merges into a ruby-red color up higher on the work, blending from dark to light. A wide range of table and ornamental wares with diamond designs or swirled ribbing was produced with Amberina glass.

Type of ART GLASS shading from golden-amber at the bottom to deep red at the top, devolped by Joseph Locke at the New England Glass Co, in 1883. Amberina was widely manufactured in the USA and was also made in a PRESSED-GLASS form in north-east England.

A type of Art Glass that varies in color from amber to ruby red or purple on the same object. This shaded effect is due to the presence of gold in the batch. The object is amber when it emerges from the lehr, but partial reheating causes the affected portion to become red or purple. Amberina, developed by Joseph Locke (1846-1936) at the New England Glass Company in East Cambridge, Massachusetts, was patented in 1883.
