There are various methods for laser engraving glass and creating special effects. Here are few:
1. Moist paper towel
Using a moist paper towel helps prevent the engraving area from becoming rough, and leads to a clear, white engraving result. Before you start engraving, apply a moist single-layer paper towel to the glass. Making sure that there are no air bubbles or overlaps. After engraving, the residue easily wipes off.
2. Application tape
Application tape can also be used to prevent the surface from roughening. With application tape, however, the engraving colour is rather greyish and not bright white.
3. Engraving without auxiliary materials
Moist paper towel or application tape is not the only options you have. You can create effects by making adjustments such as changing the colour in the graphic to minimize the effect of heat on a large surface, to optimize engraving results.
