Negatively Laser Etched Metal

James Williamson posted this on his REDTOROPE blog. It sounds like he was looking for an alternative to the really expensive TherMark laser marking ink.
Basically he used some spray paint intended for use on wood stoves. He did a lot of preparation to make sure the paint was perfectly adhered to the matal. He then created an image by laser etching away paint to reveal a negative image. I looks quite good with fine detail. I do not know how well the metal will hold up to corrosion though.
I often wondered what would happen if you painted ceramic glaze on metal and hit it with a laser. Would it cure to the metal.
