Couple hundreds of them old panes in my little house and there will be many more when I close in the back porch with them old cedar framed school windows I have to restore someday.

Flowing glass maybe but.....:

Viscosity depends on the chemical composition of the glass. Even germanium oxide glass, which flows more easily than other types, would take 10^32 years (100,000,000,000,000,000,000,000,000,000,000) to sag. Zanotto calculates. Medieval stained glass contains impurities that could lower the viscosity and speed the flow, but even a significant reduction wouldn't alter the conclusion, he remarks, since the age of the universe is only 10^10 (100,000,000,00).

From there and there are many others:
