• Innovations in the United States
J&R Lamb Studios, established in 1857 in New York City, was the first major decorative arts studio in the United States and for many years was its major producer of the ecclesiastical stained glass.
Notable American practitioners include John La Farge (1835–1910) who invented opalescent glass and for which he received a US patent February 24, 1880, and Louis Comfort Tiffany (1848–1933), who received several patents for variations of the same opalescent process in November of the same year and is believed to have invented the copper foil method as an alternative to lead, and used it extensively in windows, lamps and other decorations.
