Abstract :
A new reflector that is as efficient as a freshly silvered glass mirror, that will not tarnish nor corrode when exposed continually to the weather, and so hard that the surface can be cleaned with gritty waste without scratching, was described by Dr. Robert J. Piersol, research physicist of the Westinghouse Electric & Manufacturing Company, in a paper read before a recent meeting of the Illuminating Engineering Society meeting at Detroit.
