Black Marks On Challenging Substrates

CerMark offers several products specially engineered for optimal laser marking of glass and ceramics. These products are scientifically formulated to create a permanent chemical bond to glass or ceramic surfaces. Marking glass and ceramic with traditional methods is a significant challenge. Current marking methods tend to produce low-contrast gray or white marks. Chemical etching processes can be time consuming and involve using highly toxic materials. Direct marks with a CO2 laser are made by creating ‘micro-fractures” which frost the glass but can compromise the strength of the substrate.

Laser Recommendations

Although CO2 and solid state lasers both work for marking glass and ceramic, if you are concerned about micro-fractures, it is prudent to avoid using a CO2 laser. For marking glass & ceramic, we recommend a minimum of 15W of power for CO2 lasers, and 5W of power for solid state lasers.

Marking Time

Exact marking times will vary depending on your choice of TherMark material, substrate composition, substrate thickness, and laser power.
