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
