This kind of catastrophe also happens commonly with hot pyrex dishes and not so warm granite countertops.
I know a week has passed, but to pick up any shards of glass, make a big wad of dough (like your'e going to make bread and roll it all over the kitchen floor especially under cabinets and in the corners. Alternatively, wet /damp newspaper also seems to work well.
Glad to hear that no injuries were sustained.
