22 the glass panel 21 further includes opposite inner and outer surfaces 23 24 respectively bridged by the peripheral edge 22 a peripheral portion 25 of the glass panel 21 is defined by the peripheral edge 22 and immediately adjacent surface portions of the opposite inner and outer surfaces 23 24 respectively an open frame like encapsulation or border 30 is formed as a one piece of injection molded polymeric copolymeric synthetic plastic material the polymeric copolymeric synthetic plastic material is preferably acrylonitrile styrene acrylate polymer blended with mica glass beads at a ratio of substantially 70 90 of the polymer and substantially 30 10 of the mica glass beads respectively by weight the preferable range by weight of the blend is substantially 80 of the polymer to substantially 20 of the mica glass beads the latter ranges of the polymer and the mica glass beads achieve an extremely low shrink ratio and elasticity as compared to polypropylene as the injection molded blended polymer of the open frame like encapsulation 30 cools its virtually minimal shrink ratio parallels the almost zero coefficient of expansion of the tempered glass panel 21 consequently weld lines of the injection molded frame like encapsulation 30 will not fracture particularly when subject to temperature anywhere between u2212 30 u00b0 f to 140 u00b0 f the open frame like encapsulation 30.
