Red Glazed Tile 2W

Wanted to see what the IR would do on a glaze closer to its own frequency. I was not ready for the result. At 6000mm/min, 100% power… the IR passes right through the glaze and etches the ceramic.

Here’s a bit of a few finger swipes so you can see the glossy top glaze is untouched and the engrave is under the surface.

How curious.

Very interesting. My wife has a ceramic jewelry shop. I will show her this so I have a good excuse to get the IR laser :laughing:
