Glass Engraving

[louiecui1946]

Just wanted to share my experience engraving glass. I engraved a Tequila Glass and came out perfectly as I expected. I used pure dish washing soap. I used my finger and apply thin coat of liquid dish soap over the area

to be engraved. Place the glass into the engraver and laser through the soap while it is still wet. The dish soap is often all that is needed to protect the glass.

How did you hold it in position? I’ve been toying with the idea of doing some shot glasses (toothpick holders–some of the places I sell things aren’t allowed to sell alcohol-related items), but I don’t have a reliable way to hold them during the process

Shot Glass Jig & Template

I’m buying a Glowforge primarily to expand the range of gift and souvenir products I sell. That will likely involve low-volume production of various items including etched shot glasses. As nice as the Bur-Lane Rack Star system seems, I’m concerned about whether (A) it will fit in the limited z-height of the Glowforge and (B) how long it will take me to sell enough shot glasses to pay for it. After much thought and some experimentation on how to make a jig that will hold several shot glasses in p…

Square Shot Glass Engraving Jig

Here’s my quick journey into shot glass engraving. I created this to help my daughter engrave some shot glasses for her and her graduating suite mates at college: [35] The idea of a simple jig was inspired by @johnwills https://community.glowforge.com/t/shot-glass-jig-template/3110. I also used his 950/100 at 225lpi settings to engrave - AND - his super clever tip about a thin film of dish soap to get better results. I had 100% success on the engraves. The jig is designed for use with these…

Very nice. Great idea and thanks for sharing the soap info.

May I ask what height you set it at? (thickness) These are awesome!

what settings did you use

Since the Beyond the Manual section is the only place manual settings are allowed, that would be a good place to search. There have been a bunch of threads about engraving glass. For Example:

Help with engraving Glass - Settings (new)

I’m going to move this topic to Beyond the Manual. @tapoutms3, you can try the settings below for Engraving on glass: Power 100% Speed 850 LPI 340 You cannot cut all the way through glass with a laser though. Make sure you use a film of liquid dish soap, masking tape or a damp paper towel secured over the glass to keep it from cracking when you are engraving it.

Hi, did your glass chip out over time? Your engrave looked like mine but as soon as I washed the glass the white etched glass chipped away.

For me, the sweet spot is 800/full/450 x2. After I brush away the chips, cutting any remains with a small knife, then polish with a 2000 grit sandpaper. Wipe with some alcohol and they look fabulous!

For me, different glass has engraved drastically differently, and I had to test for all.

I have saved settings for the spice-jar lids and shot glasses, but I’ve also done cheap glass plates from the dollar store (one-time, didn’t bother to save settings.)

The spice jars I engraved are no longer available. The shot-glasses are, and I have many left.

I also tried some of my glass settings on lanterns, was not successful. I replaced with clear acrylic.

Glass is not all alike.

I meant specifically for the shot glasses referenced above
