I've not done too many recording sessions of shattered glass, but I've done a few. If I were to do a big session, this is how I would design it:
Find a nice clean cement floor, with a decent area to work with.
If the room that contains this nice area adds a lot of character to sound (like reverb, annoying modes, flutter, etc...), make some time to treat some of these problems
Outline the area you are going to be breaking the glass in with some kind of boarder. It might be 2x6 pieces of wood, metal, etc... that create a boundary to stop most of the broken glass. In my opinion, the best way to do this would be to surround the area almost completely with hanging furny pads (from the ceiling or on mic stands), with maybe a foot or so on the ground to prevent glass from sliding under them. You can secure the sides together too so that nothing gets between them. The furny pads will not only keep the glass contained and leave the sound uncolored, but they will also provide you a makeshift "booth", sheltered from room reverb.
Set up your mics (probably good to put foam or a furry on them to prevent the glass that hits the mics from making pinging in your recordings).
As for mics, I'd try a few LDCs, maybe a shotgun to add some sweetness in post, a stereo mic, etc... I'd probably try to stay away from brighter mics, such as a 416, a C414, and such. A ribbon mic would probably sound cool. But be sure to protect it!
Hope I explained myself well enough. If I need to clarify anything, let me know!
