American Victorian secular stained glass windows [1880-1910] were completely different from most painted European stained glass. Innovators like Louis Comfort Tiffany and John Lafarge utilized opalescent glass [the glass itself is extravagantly colored] and focused on illuminating the glass, to let the light itself paint the desired image.
They also frequently imbedded glass chunks as well as actual pebbles and shells in their design. Other American innovations included faceted-glass and cut-glass jewels, beveled glass, pressed designs such as scrolls and stem of flowers, folded glass that looked like draped textile, ripple glass that looked like feathers and confetti glass.
