iridescent glass perfume atomizer

I have always called this "peacock glass" but I guess the real term for its lovely rainbow color is iridescent glass. Louis Comfort Tiffany called the iridescent, silver nitrate coated glass he used, "Favrile" glass. Rene Lalique used it in his sculptural lamps and vases. This old perfume bottle is neither Tiffany nor Lalique, but its rich, glowing colors are beautiful and I love it.
