I dropped a 6.5 gallon glass carboy.
It's been 10+ years of usage and taking extra steps to be cautious with them. I usually work with them on top of wood and carry/store in a clean plastic trash can, but looked past the wood part just this one time. My hands were soapy as I was cleaning/moving it. I simply lost friction while holding, like only glass can do, and it shattered something fierce with the 1.5 foot drop over textured cement. No injuries, but two extra hours to clean up with so many tiny tiny chips and shards.
Now switching over to 100% plastic, picking up 5 22L food-grade buckets. Wow, these things are much more practical.
Why post this? I'm sure there are others like me who are aware of the dangers but use them anyway. Simply a data-point that continued use of them was more risk than I realized.
Cheers.
