ABSTRACT:
A glass system with temperature controlled translucency, utilizing plastics, where the glass system comprises a polymer blend P, formed from unlike polymer constituents P.sub.1 and P.sub.2, and has a lower critical solution temperature (LCST), where under the critical solution temperature the polymer blend is single-phase and transparent and above the critical solution temperature polymer constituents P.sub.1 and P.sub.2 separate, and where the polymer constituents P.sub.1 and P.sub.2 have different indices of refraction.
