I have not used it yet but cermark makes a black tape that when you laser it it reacts and leaves a permanent black etching. Laserbits sells it I think.

Welcome to SMC.

That tape and the liquid are for marking metals.

They do make a chemical for marking glass but it's not likely that it will work on clay.

Cermark, sent out an email a few weeks back about the tape to use on Clay Bricks, I have not tried it yet.

Just an FYI

Mike, I did a test probably 2 years ago with the Thermark for ceramics and it did fine. I've had it outside since I marked it.

I used the glass stuff several years ago but did not have need to try it on clay bricks. I have no doubt it'll work on ceramic though.

This was on a brick. I'll try to remember to take a picture of it.
