The method for engraving glass by laser engraving machine
The laser can engrave on the surface of glass but its engraving depth is not deep and it can’t cut the glass. Generally speaking, the laser can make the frost melt and crumble result. Under normal circumstances, the user want to get frost melt but not crumble result. The result is mainly up to the texture of glass and whether the hardness is unanimous.
In general, engraving glass is more difficult to control, according to the following steps we can get more smoothing frosting surface:
a. Please smear a little detergent on the engraving area, cut off a piece of newspaper or napkin whose area is much bigger than the engraving area, fully steep wet the paper with water, squeeze out the spare water, level the wet paper on the engraving area without wrinkle.
b. Put the glass inside the laser engraver, please start the engraving when the paper is wet. Then take out the glass, clear away the remnant paper and clean the surface of glass. If necessary, we need to polish the surface of glass with 3M scotchBrite. Generally speaking, the laser power needs to be installed much lower, the resolution needs to be installed as 300dpi, we can try to use the big standard lens to engrave.
Note: We need to become more careful when use the laser to engrave the leaded crystal, the leaded crystal has the different expansion coefficient, when engraving we may lead to the crackle or fracture of crystal. We can avoid the problem if we install the laser power much lower but we also need to keep fracture away at any moment.
Clean: After finishing the work, we can clean the glass surface with stupe.
Fills: We can color the glass with acrylic paints.
