Glass

Fine detail glass engraving. Slow pass with higher DPI for portrait or text on tumblers and wine glasses.

CO2 glass engrave — low power to frost without cracking. Apply wet newspaper or dish soap over surface to reduce micro-fractures.

Frost engraving on wine glasses and tumblers. UV doesn't crack glass.

Frost effect on clear glass. UV doesn't crack glass like IR.

High-power UV gives excellent glass results — frosted marks without coating.

UV laser marks glass directly — no coating needed. Cool frosted finish. Multiple passes darken result.

Glass engraving on 5W A5 Pro — wet paper towel method for best contrast.

Glass engraving on 6W diode — masking tape technique recommended.

Glass engraving on 5W diode — use wet paper towel method for best results.

Glass engraving on Aura — use masking tape to improve contrast and reduce chipping.

5W Falcon can engrave glass with masking tape or wet paper towel technique for better contrast.

Apply dish soap or wet newspaper over glass surface before engraving — reduces thermal shock and produces frosted white finish. Wipe clean after. K40 CO2 engraves glass beautifully at low power. Cannot cut glass.

Apply dish soap or wet newspaper over the glass surface before engraving. Reduces thermal shock and gives a frosted white finish. Wipe clean after.

Diode engraves glass surface but results are inconsistent. Mask with wet paper towel to reduce cracking. CO2 produces far better results on glass.

What are the best laser settings for Glass?

A top-rated community setting for Glass on the Glowforge Pro is speed 300 mm/s, power 18%. There are 79 community-tested settings for Glass across 52 machines on this page.

Can a diode laser engrave or cut Glass?

Yes — there are 43 community settings for Glass on diode lasers and 31 on CO₂ lasers. CO₂ lasers generally cut faster and cleaner, but modern high-wattage diode lasers handle most stone work well.
