Etching Glass - How to ensure it only marks one side?

Using a Falcon 10w Laser to engrave glass. Having great success with it after having painted the glass, however the laser is going all the way through and also etching/damaging the other side of the glass. How do I get it so that it only etches on the face I want and not on the inside too?

More paint? Different, faster settings? Help!


For reference, have used .02mm interval at 100% power at 400mm/m, 1000mm/m and 2000mm/m and have had same problem at all speeds.

Place the glass a little away from bed.


This worked! Great!
