Wild Rose is the name that New England Glass gave to its peachblow, which turns shades from pink to cool white. Mt. Washington glass turns from peach to ivory. Wheeling produced cased peachblow, transparent glass with an opaque white lining. Amberina, another coveted color, is amber glass that has been reheated to develop a red color on only one part of the glass. A further development is Agata, which added a mottled blackish stain to give the glass and agelike mottled surface.
Most agata pieces are small, and examples are rare.
Other designs imitated delicate porcelain. Mt. Washington s Crown Milano is an opal glass, free blown of pattern molded glass, tinted a delicate color and decorated with enameling and gilt. The craze for Victorian art glass lasted into the 20th century, when it was outstripped by the Art Nouveau creations of Tiffany and Frederic Carder of Steuben. Today s art glass manufacturers are producing amberina, peachblow, and many other art glass colors, which have become collectable in their own right.
