Glass is a suitable material for laser engraving due to its transparency and ability to withstand the heat generated by the laser beam. However, the engraving results can vary depending on the type of glass used. Some types of glass, such as borosilicate or crystal, produce better results than others.
When engraving on glass, the laser beam interacts with the surface, causing it to heat up and fracture. This creates a frosted or etched effect on the glass. The depth and clarity of the engraving can be controlled by adjusting the laser power and speed settings.
