Sigh............... I've never seen glass break apart... and raise up.......

My glass bed is filled with pot holes. I need to span those gaps. CA's advice seems to be a perfect solution.

You seem to assume that ALL printer's work like yours, that you can easily remove the glass and throw it into a freezer. Even if I had a freezer empty enough (A full household of kids kinda prevents this) to place my print into, the labor of completely disassembling the case of the printer, disassembling the Z axis, unplugging the bed from the board, placing that in a freezer, removing the print, reassembling the Z axis, plugging it back in, reassembling the case, is kind of a pain in the ass.

If you want to be helpful, make sure to read the OP's, and then respond constructively to that. CA offered a very viable, and CHEAP, solution to my problem. Not one of your comments was any help at all.
