There are several CerMark coatings for glass and ceramic marking.
CO2 laser wavelength causes cracking in glass. In order to minimize damage to glass with a CO2 laser it is essential to use low power and slower speeds in an attempt to “melt” the material onto the glass without damaging it. If possible you should always perform a power grid on a practice piece to determine the optimum setting.
In general it is easier to obtain marks on both substrates with Fiber lasers because the wavelength passes through glass and does not create cracking.
Some color materials are available for glass and ceramics. The color of the mark can vary depending on the particular settings.
We can provide customized materials for large scale projects in the kitchen/bath ceramic and porcelain markets. These products can be color matched, within limits, for specific customers.
