That's amazing. What's in the head that performs the actual carving?
It's a CO2 laser. Granite contains some amount of radium and/or uranium. This process would probably create some radon gas and maybe even a little gamma radiation.Quote:

It uses impact engraving. Laser was a good theory though. They do have laser engravers.
