Mechanical stress builds up in glass over time, so like that stupid homemade submarine, it could have been weakened and finally just blew.
I don't think thats how glass works. If it did, tempered glass would slowly lose the stress that makes it tempered.
I think I said the opposite of that? Tempered glass does just suddenly blow up sometimes.
Anyway, I was a glassblower for 15 years and yes, mechanical stress builds up in glass over time as it gets bumped, tapped or knocked around. Small scratches and nicks can significantly weaken older glass too.
You are right, you did. And being a glasblower you certainly have more experience with glass than me.
But it still feels wrong, to me, that the stress built into a glass body changes over time. Damage, like you say, can of course introduce failure points.
I'm tired and I might have misunderstood you and perhaps we are saying the same thing or talking about completely different things
