Engraving in glass is a substitution for sand blasting. Nowadays the engraving does not have to be only white. Thanks to sprays, which are sprayed on the glass before the engraving itself, we can have also a black engraving today.
Glasses and bottles belong to the traditional articles of glass and there is no problem in placing them in the engraving machine thanks to the rotary adapter. Further small glass tablets and trophies, of course.
We can engrave only glasses in this way. Unfortunately, we do not have a rotary adapter for the CNC machine at present.
