Photoelastic examination is utilized to determine stress in glass, which features a carefully filtered light of a single wave length
In some stress studies, a custom built polarimeter is used

OMPLETION of three n e w buildings
adds one quarter of a million square feet of floor space for laboratories a n d offices of Corning Glass Works, Corning, Ν . Υ . This new construction represents one of the largest in t h e company's 106year history. T h e nine-story administra tion building, three-story research labo ratory, and one-story development work shop were needed t o meet space r e quirements resulting from rapid growth in t h e past decade.

OF THE MONTH
Laboratories, are named in honor of t h e founder of organized glass research in the United States. These two buildings house laboratories, offices, a library, a 100-seat auditorium, a n d conference rooms. Allowance is made for 2 0 % fu ture expansion. B y doubling t h e space available, Corning will be able to continue its sub stantial research program more effi ciently. Research is t h e life blood of Coming as indicated b y t h e fact t h a t 7 5 % of its present sales are for items which did n o t exist 15 years ago. A
The 68,000 square foot development workshop faced with glass blocks and the 60,000-square-foot, three-story research laboratory faced with black Carrara glass comprise the new Eugene C. Sullivan Research Laboratories. More than 350 chemists, physicists, glass technologists, and assistants use these facilities for re search on glass and ceramics
good example of a fundamental research project yielding a new product is t h e development of a new family of crystal line materials made from glass. Called Pyroeeram, these materials are tough, heat resistant, harder t h a n steel, lighter than aluminum, and nine times stronger t h a n plate glass. Research efforts a r e directed along several lines including fundamental, chemical, melting, refractory, television, electronic components, technical serv ices, and consumer products. The best in instrumentation is r e quired in these operations. One typical example is precision photomultipliers and associated electronic a p p a r a t u s used t o study crystal formation. A c curate time measuring devices, which will measure accurately t o a t e n t h of a millionth of a second, are* used regu larly. Under development is one which will measure one millimicrosecond. I n the television field, much research h a s been done in developing better glasses for television tubes a n d for sealing t h e faceplates, cones, and neck components. T h e Chemical Research Group centers its research on t h e chemical stability of glass (reaction t o various acids a n d bases), new glass compositions, a n d further development of high silica glasses (Vycor). Considerable work h a s been done on glass solders for sealing metal t o metal, glass t o glass, glass t o ceramics, a n d glass t o mica. F u r t h e r development of glass as a high tempera ture lubricant is also under way. VOL. 29, NO. 9, SEPTEMBER 1957 ·
