This very elaborate vase is not signed, so it is impossible to attribute it to a specific glasshouse. It is clearly a unique piece, probably made by a mid-19th-century glassblower on his own time. The rough pontil mark supports this conclusion. If the piece had been part of the factory’s production and intended for sale, the mark would have been polished. Most of the threaded pieces made during this period were produced by glass factories in western Pennsylvania and southern New Jersey, but the neatness and precision of the work on this vase make the New England firm a more likely source. The applied and tooled gather at the base of the vase is unusual for that company, but not unknown. This vase is similar to one in The Metropolitan Museum of Art that is also attributed to the New England Glass Company. Founded in 1818, the firm continued to operate in East Cambridge until 1888. For the first 30 years, it was directed by Thomas Leighton, an experienced English glassblower. After his death in 1849, his son, John H. Leighton, served as superintendent until his retirement in 1874. A number of pieces that descended in the Leighton family were given to the Museum by family members, so the Corning collection contains examples of various types of decoration attributed to the company and made between 1818 and 1874. [228 words] The most comprehensive history of the New England Glass Company and the Leighton family is Lura Woodside Watkins, Cambridge Glass, 1818 to 1888: The Story of the New England Glass Company, Boston: Little, Brown and Co., 1930. The author interviewed several surviving members of the family, and her book includes a chapter on the Leightons.
