does somebody work with large cast glass objects? What are the physical properties of cast glass, and, more important, what are the strength properties under high compression stress?

-the largest cast glass items are done for astronomical telescopes at Tuscon Az, many meters in diameter,special materials, very uniform, low thermal expansion
-when loaded uniformly glass will usually hold up under 40KPSI or more, about 1000psi under tension - See Yoder, books on optical component mounting SPIE press
Schott has data on failure of glass with rate of application of load - not the same as static loading
Commercial gass glass probably somewhat less
-See McLellan & Shand Glass Engineering Handbook McGraw Hill
