Personally, only one and that was wiping the rim that had some sediment from a bad pour. Snapped the stem and the rest shattered into a million pieces(although I like the atoms reference). My hands are not built or wash these glasses so my wife has broken about 7. Not a blame, just a function of time.
Probably about a dozen over the past 20 years. But the only four that really hurt were the 4 Gabriel Glas Gold’s that I killed in less than a two year span. Having much better luck with Grassl Liberte’s (thus far)
I wear gloves when I hand wash, but only broke a few washing. The drying I’ve had plenty of breaks and an occasional cut, almost always due to distracted drying. Had two glasses break in a row with the same exact break.
So many that the rule in our house is that I am not allowed to wash glasses the same night I drink out of them, regardless of how much has been consumed. Sadly, that rule hasn’t stopped the carnage.
