Glass & Ceramic Marking

The CO2 – Carbon Dioxide laser wavelength causes cracking in glass. In order to minimize damage to glass with a CO2 – Carbon Dioxide 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 YAG or Fiber lasers because the wavelength is invisible to the glass and does not create as much damage.

Some color materials are available for glass and ceramics. The color of the mark can vary depending on the particular settings. In other words if you were using LMC – 6013, blue, you may get different shades of blue depending on the power and speed.

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.

The most popular material for Glass and Ceramic marking is Black, LMC – 6044. It is available in both a liquid and aerosol spray can.
