Divot pulled from glass bed

Pyrex is a lot stronger and more heat resistant. Very different than window pane. Not likely to chip as easily. you can scratch it however.

I have the nominal 1/8" borosilicate/pyrex plate installed and have done a few test prints. First observation is that the boro is a full 1 mm thicker than the window glass (3.2 mm vs 2.2 mm). It looks very beefy on my heated bed!

It also seems to distribute the heat more evenly across the bed, as theory would suggest. This is a very unscientific observation, and might just be wishful thinking. But the extreme edges of the boro glass seem to be hotter than the plate glass was.
