I've got a glass box that measures 900mm x 450mm x 450mm.
The width of the glass is 6mm thick.
If I drill, cut, or grind a small hole in/through one of the faces; will it significantly affect the structural integrity of that piece of glass?
I'm concerned it might become prone to cracking, if for instance, I pick it up to move it.
I thought there might be some kind of ratio, or formula I can use to determine a safe size for a hole, a safe distance from the edge, and so on.
