When Fenton resumed production of their iridescent glass in 1970, they decided to call it "Carnival glass'' and have done so ever since. The secret of Fenton Carnival glass is the special spray of metallic salts on the glass while it is very hot. We never cease to marvel at the rainbow of colors and the interesting hues. This 17'' Carnival Glass Ruffled Shade Lamp features a lovely floral design. Each Fenton lamp is mouth blown by a skilled craftsman in the 100-year old Fenton factory. Decorated shades are handpainted by talented Fenton artists who proudly sign each completed piece. You can see larger photos by clicking here or visiting our website.
