That said, you can recycle broken glass and even get paid for it. I don't know if they're doing this or not, but it's probably more worthwhile than seeing if someone else needs exactly the same custom glass as you do.
Finally, unless that was a some kind of standard stock size (in which case you should be able to sell it directly to other parties), I really don't think the factory would want it back. We do mostly custom-sized lites of glass and when an order is cancelled or returned for whatever reason, it goes into the dumpster and gets recycled. There's almost nothing you can save most of the time and yes, I've searched through orders just to see if there was anything we could salvage. You're not likely to find anything you can save.
