Engraving Stones

Engraving Stones

Here are the important things to know when engraving on stones with a laser.

 

-Only engrave stones that are dry.  

 

-Measure your stone.  Is it small enough to fit in the laser without removing the tray? If not, remove the tray and build up a platform for the stone to sit on until it is at the correct level for engraving.

 

-What kind of stone are you engraving? If you are engraving colored glass stone it helps the engrave to come out better if you cover the stone with a thin layer of liquid dish soap and engrave while the dish soap is still wet. 

 

-Secure you stone to the laser bed.  You can do this with play dough, honeycomb pins, tape, modeling clay, scrap material, etc.  Just make sure it isn’t going to move when the laser starts!  Try and level the stone out flat as much as possible so that you get an even engrave.

 

-Outlines engrave better than lots of small details on most stones, especially glass.

 

-After engraving wash/clean the stone.  

 

-If it is hard to see the engraving you can fill the engrave with paint so that it stands out more.  You can engrave the stones masked if you want to paint and not have cleanup after.
