Mt. Washington Glass Works Boston, Massachusetts, 1837-1868. Moved to New Bedford, Massachusetts 1868-1894 when it merged with the Pairpoint Glass Company. Remembered primarily for beautiful art glass. Glass artist Frederick Shirley developed a method for making 3-layered, two color Pearl Satin blown ware. Amberina, Rose Amber and Burmese were 2-color lines made by using gold oxide in an amber batch of glass and reheating one part which turned dark red for a two-color glass.Company Link
