the voltage polarity causes the ions and associated electrons to return to their original layer, the counter electrode, and the glass clears. This solid state electrochromic reaction is controlled through a low voltage DC power supply. When the SageGlass coating darkens, the sun’s light and heat are absorbed and subsequently reradiated from the glass surface to the exterior.
