Default Re: Care of Rare Valves

I thought the idea of glass flowing over time was a myth that has been disproved. For instance there are many examples of Roman and Egyptian glass items that are thousands of years old and show no distortion whatsoever.

I may be remembering this wrongly.

Cheers,
Steve.
