In solar glass specifically, small amounts of antimony oxide help stabilize optical properties under years of UV exposure, reducing “solarization” (the tendency of glass to brown or

Solar glass can be either low-iron paterned glass or low-iron float glass. Both can be recycled if the quality is acceptable, but this depends on the glass composi on and the end product to be produced.
