Covered Box, 1898-1901. Louis Comfort Tiffany (American, 1848-1933), Tiffany Glass & Decorating Company (American, New York, 1892-1902). Favrile glass, enamel on copper; diameter: 13.1 cm (5 3/16 in.). By 1900 Tiffany had expanded his empire by increasing the firms production of “fancy goods,” including inkstands, candlesticks, clocks, small boxes, desk sets, tea screens, and other functional objects. Along with the array of artistic glass designs from his factory in Corona, Queens, works in ceramic, bronze, other metals, and even jewelry abounded. These smaller, more affordable luxury items were designed with as much thought to artistry as the great stained glass windows and lamps through which the firm enjoyed unrivaled success.
