The Northwood glass company was a manufacturer of art glass in various locations in the United States from 1887 to 1925.
Harry Northwood who founded the company was the son of John Northwood, a noted maker of English cameo glass. He came to America in 1880 and worked at J. H. Hobbs, Brockunier and Company. He worked as a glass etcher there from approximately 1881âÂÂ1884. He then worked for the La Belle glass company and during a strike there moved to Phoenix glass company in Pittsburgh, Pa. He became a glass maker when he returned to La Belle about 1886.
The original Northwood Glass Company was established by Harry Northwood in 1887 in Martins Ferry, Ohio. However, the company was later relocated to Ellwood City, Pennsylvania, where it failed to thrive. In 1895 he opened up the New Northwood glass company in a factory previously owned by the Indiana Glass company in Indiana, Pennsylvania. This factory joined National glass conglomerate in 1899.
In 1902 Harry opened the Harry Northwood and company factory in Wheeling, West Virginia. The factory had belonged to the J. H. Hobbs, Brockunier and Company. It was here that he developed his formula for Carnival glass.
Harry Northwood died in 1919. The company continued producing glass, but was closed in 1925.
Golden Iris was the name of the first caravel glass treatment that Northwood developed in 1908. It was known for its marigold color. The other carnival glass treatments made by Northwood were Emerald, Azure, Florentine, Perl, and Pomona. Carnival glass is identified by the color of the glass, not the color of the treatment. Base colors for Northwood were green, amethyst, and cobalt blue. Ice green, white, and ice blue were the names of the pastel colors. Northwood also made custard, stretch and opalescent glass.
Some of the patterns were:
The most common Northwood maker mark was an underlined capital N centered inside of a circle. Not all pieces carry the mark but it is seen most often on carnival glass items. L.G. Wright also used a mark like it, but was forced to stop using it.
