Standard playfield glass is 43" x 21" x3/16"
Must be tempered
Usually ask for no tempered logo on the finished glass
If for some reason local law requires the tempered logo, ask for it as far in one corner towards the edge as possible
Edges should be smooth, but don't need polishing or special finish as the edges won't be exposed
I usually get a quote for 10 or 20 sheets at once, and go in with other local pinheads, to bring the price as far down as possible
Best price I have gotten locally is 25.00/sheet, the same as I used to be able to get glass at shows, before dealers stopped bringing glass to shows
You can get vastly different prices from different glass shops - pays to ask around
