Excerpt from Data on Ultra-Violet Solar Radiation and the Solarization of Window MaterialsSome years ago special window glasses were put on the market for transmitting the short wave length ultra-violet rays of the solar spectrum, shut out by common window glass. Early in the spring of 1927, reports came to this bureau that these glasses appeared to be losing their transparency as the result of solarization, which is the designation of the photochemical reaction most of these glasses undergo on exposure to sunlight.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
