By the early 1890s tiffany had proved himself a skilled glassmaker, developing a method whereby different colors were blended together in the molten state, achieving the subtle effects that he used mainly in stained-glass windows. The application of this technique to three-dimensional form did not take place until 1893, when Tiffany founded his own glass furnace at Corona, Queens, New York. Under the direction of Arthur J. Nash, who mastered the medium as manager for the firm of Thomas Webb in Stourbridge, England, before coming to America, the new company began to produce ornamental vessels. These Favrile vases, as Tiffany christened them, soon earned him international acclaim after they were first exhibited in his showroom in 1893.
