I’ve learned a lot about tempered glass. Why? Because when what is essentially a wall to my home shatters and collapses, the inquisitive mind might ponder the reasons, especially after receiving replacement price quotes. Turns out, the tempering process compresses the inner portion of the glass, which makes it stronger than normal glass, but also prone to shattering once compromised.
As for what compromised it, I’m guessing that fell simply to the age of the door. Perhaps the glass could no longer flex properly under temperature fluctuations as the synthetic components hardened with age. But whatever the reason, the fracture was spontaneous and without obvious reason. And I was standing nearby at the counter when it happened. And it was disconcerting.
And expensive–did I mention that?
This will be followed up on, post-fix.
