Laser Marking of Glass
Flexible Engraving or Ablation/Fusing of Colored Additives
Engraving with CO2 lasers is the prevalent method for glass marking. Compared to mechanical engraving, sand blasting of etching, the lasers is considerably more flexible and faster. 2 or 3 D images can be produced within glass blocks through small dotted micro laceration. The glass must be right of high quality as well as smooth and homogeneous.
A specialized foil has been developed for the marking of glass surfaces in various colors through fusing the foil with the surface. Selective ablation of colored coatings or fusing of vitreous enamel is possible with the laser marker as well.
