PPG Starphire architectural glass, $1500
10.0mm thick, 4x8 foot sheet, heat-tempered.
4x8 is full blackboard size. Your choice if you want to use a smaller size. This low-iron glass is the only material I have found which is transparent enough for light from the edge to reach the center of the board (passing through 2 feet of glass. See the FAQ)
Talk to your glass supplier about the necessity of obtaining glass that is not marred in the tempering process. This has been a commonly reported problem.

Glass panel standoffs
These hold the low-iron glass to the frame. Your glass supplier should provide them. It's important that metal parts not contact the glass directly; only nylon parts touch the glass.
