PROPERTIES OF SOME VYCOR‐BRAND GLASSES
Martin E. Nordberg
Physical and chemical properties are discussed for Vycor‐brand 96% silica glasses prepared from glasses of lower silica content by a leaching process, and a brief résumé of this process is given. The intermediate porous glass and a translucent or white opaque form of the final 96% silica glass made by the Multiform process are briefly described. Ultraviolet and infrared transmission characteristics of glasses No. 790 and No. 791 are given.
