8 Ways to Engrave Glass!

Welcome to The Laser Channel where we Learn, Create, and Share!
Follow along as I show you 8 Ways to Engrave Glass!
Engraving glass is just one the many popular items to engrave with your diode laser machine. In this video I'll cover how engraving works, the masking agents I use, and the results!
I'm using the Atomstack A20 Pro 20w in the video but any 5 watt 10 watt, or 20 watt machine will work including Xtool, Jiccoda, Ortur, Comgrow, Sculpfun and many others.
** As mentioned in the video there is the use of Cold Galvanizing Compound spray- this is Zinc spray paint and produces hazardous fumes when spraying, drying, and laser engraving- I recommend NOT to use this method**

Thank you soooo much for putting this together. I’m a newbie. I tried the Rustoleum spray paint method with black and white matte colors. The black had white etching and the white black etching! And if you run it under hot water, it breaks down and peels off with having to really use acetone. Again, wonderful job!

[@thelaserchannel1]

Thanks! Love the tip on the hot water clean up!

[@ainttakenanyshit]

As the white paint contains Titanium Dioxide, it will burn black/dark when heated. The heated TiS02 will BOND to the glass or tile and have a black finish....

Thanks for showing all the different methods. Have only tried the brush-on tempera paint until now and got good result with it, but will definitely also try one of your other suggestions.

[@thelaserchannel1]

Thank you! I like spraying on the tempera, it takes a little longer but I find the results turn out great!

[@SarbarMultimedia]

Because CO2 laser wavelength at 10,640 nm requires no special preperation to engrave glass because at that wavlength it is opaque and absorbs all the light energy, . A diode laser operating at 455nm wavlength is exactly the opposite (as you mention) and is transparent and does not absorb any light energy. Thus it requires a surface film to absorb the light energy,and convert it to heat energy that in turn damages the glsss. This is an excellent exploration of some of those heat transfer materials and compares how efficiently they damage the glass surface. Tempera paint works because the black pigment is carbon, a great energy transfer medium. The black poster card will have carbon in its pigmenetd surface also. The cold galv paint is typically 95% zinc micro particles and zinc is also a pretty good light energy absorber at 455nm. The surprise was the chalk paint, particularly how white, crisp and uniform that result was. When I looked up the absorption spectrun for CaCO3 (calcium carbonate) I found it was similar to carbon black pigment (tempera paint), titanium dioxide and magnesium oxide. So these are materials I will have to examine further. Your painstaking thoroughness with each method is to be priased and the time you dedicated to this task has stimualed many questions beyond smple visual comparison Your results have provoked me to test additional energy transfer materials and investigate why some materials/methods produce different shades of grey/white on the same sheet of glass. . Maybe it was just the light but the text on the dabbed tempera text seemed the whitest.

[@thelaserchannel1]

Thanks for your comment and I'm happy you like my the methods! Let me know if you come up with another way to engrave with common material coatings! Cheers! 😀

[@jakerazmataz852]

Thanks for your time making this. Why is it the best ones are always the hardest and messiest. I like the chalk one, this is the first time I've seen that. But the backer board is nice and so clean and easy. Could you do more DPI on it?

[@thelaserchannel1]

You're welcome- thanks for watching! I've found really high DPI did not add more resolution or sharpness to my engravings because the size of one engraving dot on glass is rather large. It's always a great idea to experiment around and find the best settings that work for you! Have a great day!

[@karlbuckles7192]

Excellent and very informative! Thank you!!

[@thelaserchannel1]

Glad you liked it!

[@shawnmurray7232]

Most interesting is that the cold galvanizing appears to have darkened the engraved glass. I'm guessing that's because some of the zinc from the paint is melted into the glass, and zinc tends to darken as it oxidizes, acetone quickens that oxidation. Speaking of.... harsh chemicals are not needed for cleanup. You can use a razor blade scraper on areas that haven't been engraved to scrape away the paint. Then, I just use soap & hot water for all my paint cleanups on the engraved glass.... the trick is, I use stainless steel wool to scrub it down. Stainless Steel is softer than glass so it won't scratch the glass, but it easily removes the paint. It's expensive, but a single ball of stainless steel wool has lasted me 3x longer than a whole package of regular steel wool.

[@wsparry1066]

Great video,I have a atomstack S10 if focus on the material and not the glass the laser head touches the glass

[@thelaserchannel1]

Thanks! Yes- the transfer method of using black poster board with the clear glass on top can run into issues if the glass is really thick. In this case using a masking agent like the tempura paint on the surface closest to the laser is a better option.

[@wsparry1066]

Thank you 👍

[@CATANOVA]

Another way of doing it. Apply some adhesive film to cover the glass completely. Use the laser to cut the film as per design peeling larger sections where necessary. Using a small sandblaster attachment for your compressor sand blast the glass to produce a frosted appearance whereby the remaining film performs the function of a mask. Finally remove the remaining adhesive film.

[@thelaserchannel1]

Great idea- thanks for sharing!

I found your video to be really interesting. I am having trouble engraving glass with my diode laser engraver. It is the xTool F1. I tried a few methods with varying degrees of success. I tried tempura paint which I applied with a foam brush but that gave an uneven texture to the engraving. I then bought a Preval sprayer, which is an aerosol spray can with a tube that comes out of the bottom into a jar that you fill with liquid and you can spray onto surfaces. The watered down tempura paint went on a lot more evenly but still there was a ragged texture to the finished engraving. Finally I bought a bottle of matt black chalk acrylic paint and watered it down and sprayed that onto the glass. I was on evenly and had a much less shiny finish, but still there was a ragged unevenness to the finished engraving, particularly at the edges of the engraving. From your video you said your diode engraver was a 20 watt machine, the xTool F1 is a 10 watt machine. Do you think it is not powerful enough for a clean result in glass engraving? Thank you for your time.

[@thelaserchannel1]

Hi and thank you for the compliment- glad you enjoy the videos. When I sprayed the watered down tempura paint- the fist coat was just a very super light dusting- another 2-3 coats and I had an even coat. As you found out an even coat of the masking agent is key to a uniform engraving. The masking agent and the glass will effect the engraving texture. A 10 watt laser is plenty to engrave glass! If you find you're still struggling I would recommend posting the Xtool Facebook user group- you'll be able to post photos/video of your settings and results- it's a very knowledgeable and responsive group! Best wishes!

I need to try method 4 and 5. I do a lot of engraving on glasses for breweries ( just finished a batch of 300) and do not use any masking or even water. Will be interesting to see the results and how much time it adds to production. Right now I engrave, lighting sand to take off glass shards, and then box them for the customer. Then they throw them all in a commercial glass washer to clean them. I have two 40W CO2 lasers and one 50W CO2 laser. Thanks.

[@thelaserchannel1]

Excellent- thank you for sharing!

[@TheBlairHouseProject]

CO2 uses a longer wavelength of light and it cannot "see through" regular silica glass, so doesn't need the coating like the diode lasers do. If you play with an IR camera you will notice it cannot see thru a window.

[@melannieworld]

What would you us for ceramin plates?

I haven't engraved ceramics too much. Each type of ceramic and coating are different. I would recommend running materials test chart to find the best settings for your setup and material!

Hello, I really enjoy following your videos. I'm writing to ask for your advice on something. I'm using a KT10 3W laser machine, and I've tried Black, Yellow, Blue, and Green paper on glass, but they all burn, and I end up with a white/grey result. When I tried Red and Grey paper, I achieved perfect colors. I can't understand the difference. Do you have a setup recommendation for Black, Yellow, Blue, and Green papers on glass

[@thelaserchannel1]

Thanks! For the papers- are you just looking to transfer the energy of the laser to the glass to engrave a frosted white look? I've only used 1-2 colors for this method - I stopped when I found a method that works :) I do know that different colors of paper will react differently with the laser diode machines- and will need different settings.

[@magnogkilla]

@@thelaserchannel1 First of all, thank you for your quick response. I want to reveal the color of the paper on glass, but the color is not coming out. It turns grey/white, probably because the paper is burning. I increase the speed and lower the power, but then the design doesn’t stick to the glass. I can’t seem to figure it out. Here’s an example video. I can’t seem to achieve a proper black tone, or the quality is poor. What would you recommend for a 3W machine? I want to design glasses as a hobby.

Hi, Thanks for the great vid. What is your recommendation for Glass trophy engraving- co2 or laser? Thanks, Much appreciate your opinion.

[@thelaserchannel1]

I would recommend a Co2 laser if your budget allows. A Co2 laser can directly engrave on clear glass with no need for a masking agent. The same for acrylics- solid, clear, or translucent- a Co2 laser can cut or engrave any color. The diode lasers are nice and can offer a lower price point, longer life laser source, and less maintenance needs.

[@balwn4127]

[@TheBlairHouseProject]

Are all these labels as resilient as each other? Can you film scrubbing them with a scourer or steel wool to show how well they hold up? Perhaps put both sheets thru the dishwasher a couple of times to see if there is any fading?

[@thelaserchannel1]

The engraved glass truly is marked into the glass! Not amount of scrubbing or dishwashing will remove it! There are some methods that produce a black engraving and all reports come back that the color does wash off in the dishwasher- the color lasts longer when hand washing. By touch there is texture in the engraving that goes into and penetrates the glass! Thanks for watching!

[@TheBlairHouseProject]

That's good to know. The cold galv one is darker (which I do like)... does that fade over time or is that integral into the glass? My replacement engraver doesn't get here for a few more days and I cannot test until then. Whomp!

Question on speed and power settings: Did you try with higher power and speed? Just wondering why you dialed the laser all the way down to 65%? Did you ever get the glass to fracture completely with the laser?

[@thelaserchannel1]

Good questions- I purposely kept the settings all the same. This way if someone is already using one method and have it dialed in they can see the engraving difference for more or less engraving effect. I have not been able to crack glass with a laser diode- only with a Co2 laser.

[@TheBlairHouseProject]

@@thelaserchannel1 was there any disadvantage to going 100% and correspondingly faster (e.g. 100% at 9000mm/min). I have not gone down the CO2 rabbit hole yet! lol

[@thelaserchannel1]

@@TheBlairHouseProject Nope- just as long as the laser can transfer enough energy into the masking agent to the glass. Some people will also say running a laser diode at 100% will shorten the life; I somewhat agree but by the time that happens the machine is usually outdated and ready for replacement. BTW- Co2 lasers do not need any masking agent to engrave glass and run at much lower power levels- I've actually cracked glass with a Co2 at too high of power!

[@TheBlairHouseProject]

@@thelaserchannel1 Have you ever managed to cut glass in a controlled way with a diode laser ? (i.e. not a random fracture). If so could you share how or post a vid? Not much out there about that, but the diode lasers have gotten a LOT more powerful in the last couple of years.

[@thelaserchannel1]

@@TheBlairHouseProject A laser diode operates at frequency or color of light that does not directly interact with clear glass or acrylic. This is why we use a masking agent like tempera paint. The laser energy is absorbed by the the masking agent and then transferred to the glass. To cut glass a Picosecond laser is needed- very expensive. Edit- its' not power of the laser diode that prevents it from cutting glass, it's the color of the laser beam.

I appreciate the thoroughness of the methodology. One thing I don't get is, why expose two methods told to be dangerous, and say it should not be used? What is missing too is a comparison of results, beyond just showing them. What gives the finest look, what is the most contrasted, etc. Pro and con of each method. Also, I regret your project is only black & white, no gray image engraving. It would have been interesting to see the results for that too. Lastly, I have seen elsewhere methods with some wet paper towel over the glass, using masking tape, or using a fine layer of dishwashing gel. Perhaps you might want to try these too? (I haven't tried that yet.) Anyway, your video is well made, thank you.

Thanks for watching and I appreciate your feedback. I covered the two hazardous methods to show they yield the same results so the health risks are not needed. The results- I like people to see for themselves and balance the time to apply the masking agent vs. the results- this also helps keep the video kinda short. I have tired masking tape and it does not work.

It is the same paint the utility company uses for gas meters, etc. You should not be breathing in *anything* that comes off a laser cutter. Or anything that comes out of a spray can. It's all bad for you. All my cutting is done in an outdoor covered area with a fan on. We are all adults here. I am pretty sure one disclaimer is plenty, and no one is going to hold you responsible if they get cancer in 20 years. ;-)

Thank you- The Cold Galvanized paint is by Rustoleum and I agree 100% that breathing in any laser fumes is bad! The Cold Glav fumes are even worse and I do not recommend anyone to use it because of the health risk and there's other easier methods to mask the glass! Thanks for watching!

@@thelaserchannel1 What I asked is did you mix the galv and red? The red also says it has galvanized (i.e. zinc). Was the red coating just only the red paint and nothing else?

@@thelaserchannel1 Have you found anything else that gives that darker etch finish (that is permanent and not worn by washing)

[@thelaserchannel1]

@@TheBlairHouseProject Ok- I understand, the red paint is Ultra Cover primer+paint. I did not mix the red paint and the cold galv paint.

Nice :) Yes, I'm watching the length of the video and try to keep them a bit shorter. There's that balance of enough detail for new people and keeping the video moving along for experienced people. Thanks for watching!

Spent way too much time on stiff like the cleaning when you should have fine slower on the finished images getting closer without moving so much. Hard to see how crisp the lines really were. Thanks

You should get money back from whoever finished that wall behind you
