Laser Settings for Mirror
Can you laser engrave a mirror?
Yes — and the trick catches everyone out: you engrave the back, not the front. Flip the mirror and work through the rear paint and silvering, so the design reads bright and clear when viewed from the reflective face. Works on CO2 and diode.

✓ EngraveWork on the painted back, not the front — the beam won't mark the reflective face usefully.

PrepPreparation & technique
Clean the back, then engrave your design (no need to mirror the artwork — engraving the back flips it for you when viewed from the front). Support the glass flat and evenly.
⚠ SafetyFine glass and paint dust — extraction on. Handle engraved edges carefully.
