I wouldn't let it go that hot again. The infrared gun aimed at the tstat will give you an indication of a faulty gauge. If gauge is ok, you have a bad stat, or some kind of blockage, ie a shipping plug left on radiator inlet, etc.
Is the TStat a GM piece? It should open, and you should see water moving in radiator before 210. If not, shut it off.
