Glass place said there would be no problems with having holes drilled in the glass before it was fired. I was thinking 1/4" in from the edge, two per side asymmetrical. I mean I will just put some rubber grommets behind the screws an caps over the tops of them, should look really clean IMO. I am not suspending the glass here, just holding it in place from tipping forward.
Ya know thinking maybe even two per side is two many, maybe I should just do the 4 corners or two on the left and right?
