Never underestimate the utility of brute force and ignorance -- it may be ugly, but it's often effective
It will work. Go slowly at first until you find the best angle and force needed. Wear goggles and gloves. Be careful you don't cut into the actual hull. Keep a whetstone or equivalent handy to sharpen the chisel, 'cause the glass will take the edge off pretty quick.
Another option is a oscillating tool (like a Fein MultiMaster) with a carbide grout removal blade. It'll still generate dust, but tons less that an angle grinder. If you keep a vacuum hose right by the cut, it stays pretty clean.
