cast glass

(OP)
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?

RE: cast glass

-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
