The Glow series is made up of glass tesserae that display a wavy surface with iridescent reflections. They are produced and colored with oxides that, fusing completely with the glass, allow the creation of pure colors. The wavy effect is obtained through the use of a special mold. The iridescence, instead, is achieved by spraying a chemical product on the incandescent glass tesserae that, reacting to the heat, produces this very sophisticated, elegant effect.
