Non-semiconductor ceramics come in a variety of shapes and forms.
Some are very soft and others are hardened providing a lot of variety.
In general, ceramics are a difficult substrate to laser mark as they do not typically absorb a lot laser light or wavelength.
ZGG Laser offers a 532nm Green laser marking system that is better absorbed by certain ceramics.
We recommend you have test sampling done to determine the best marking technique to apply to your ceramic material.
Ceramics that can be marked are often annealed, but etching and engraving are sometimes possible, too.
