Laser Engraving Glass With a Diode Laser

In this video, we will be laser engraving glass to get a white, frosted image onto glass coasters. We will use cold galvanizing compound (use Cold Galvi in a well ventilated area. It is toxic.) and non-toxic tempera paint as our coatings. Our laser is the XTool D1 10W blue diode laser.

I've learned a great deal from this video in my quest to etch acrylic mirror tiles. New things about lightburn I didn't know about in a whole year of using it (renewed subscription 2 weeks ago). Appreciate the vid.👍

[@morganclapp5554]

i don't subscribe to many people at all but after getting a diode laser and hearing all the snot head c02 users say all kind of junk about what we cant do, i'm glad i found your channel

[@LaserNoob]

Thank you for watching and I hope you continue to find the content useful!

[@billfuller317]

I use water and a scrubby to clean off cold galvanizing compound. I liked the way you did the paint, no brush strokes, how cool!

[@LaserNoob]

Great tip!

[@edriveria64]

@@LaserNoob Does the engraving settings change when using the xTool Creative Space instead of Lightburn?

[@LaserNoob]

Power and speed settings should not change between programs.

[@nq0amark138]

Hands down winner on the tempura paint and a lot less time. If one is doing a batch run of coasters air brushing the tempura paint would be a fast way to paint. I vote for the tempura and that's what I will be using. Great video and informative ! Cheers.

[@hesidoabducido7]

Damn you are no noob sir, these are SKILLZ! You saved me from going for a CO2, a diode covers all my needs now. Thank you great video.

[@jakerazmataz852]

It's about time. If you got it, a 5w will do. If not a 40w. Also, $$$.

[@LaserNoob]

I did another glass video with an atomstack 5w. :)

[@jarodmorris611]

Thank you!!! I don't know why so many creators don't say much if anything about how long the burn / cut takes.

[@K1ng9888]

I am new to the craft.... lets just say I have heard 3 ways... gal spray, tempera paint and cardstock.... also reversing side...... so far ... I realized I already have tempera paint (My wifes crafts), used that.... no reason to change. thanks for getting straight to the point and reinforcing my experience.

[@LaserNoob]

If I ever get 40w laser, I'll go back to cold galvi because it gives the best white. Until then, tempera is the only way to go in my book. (Without buying a ridiculously overpriced can of laser spray)

[@KatieGent-y6s]

So easy to understand and follow !! Love these viedos

[@LaserNoob]

Thank you!!

[@bellofbelmont]

Thanks. I'll try the Tempera Paint. I have a 10 watt Snapmaker Artisan. Jim Bell (Australia)

[@xtrememaproductions]

I experimented with dry erase marker with the clear acrylic works pretty well I think it also works on glass as well.

[@jimhinkle7245]

I appreciate your videos AND your mistakes. Both teach us a lot!!!! To me, the white on the Cold Galvi isn't worth the extra hour and a half burn time.

[@LaserNoob]

Agreed! And thank you

[@dbrimmage237]

To get a cleaner edge/outline, you might do a line after fill.

[@jakerazmataz852]

From the videos I've seen, and I'm new, it seems that should be the norm.🤷‍♂

[@jimking9646]

very nice

[@buckshotl1678]

You're cool when you say galvy

[@LaserNoob]

Not sure if you're being a smart ass or not, but cold galvi is a common term in the HVAC industry which I have been in for 30 years. If you just want to be a smart ass, consider yourself educated while you feck off.

[@arturolaraya3024]

EXCELENTEEEE!!! MUCHAS GRACIAS POR COMPARTIR

[@LaserNoob]

De nada, amigo!

[@willyD801]

I usually use the cold galvanising. But I'm not sure why you need the chem to clean up the cold galv. I use water and it easily cleans off glass. I'd say it comes off as easy as the tempura maybe even easier. I'll need to look at my test grids again. Some how I didn't notice that the cold galvanising was so much slower.

[@chrisrichie915]

Thanks for the comparison... at timepoint 20:24, you say that the 354 DPI for tempura was "higher" than the optimal DPI for cold galvi, but I could not find an explicit statement for the final DPI settings for cold galvi. can you show a screen shot of the "cut setting editor" for your final cold galvi run? (or report out the details in a reply?) THANKS!

[@nhums]

Great video, I'm new beginner to use Laser engraving . 2:34 What liquid in the clip is used to mix with Tempera paint? Thank you in advance

[@LaserNoob]

I thin it with water.

[@kamransfrli3700]

Hi u add 150 ml tempra paint and 50 ml water?

[@LaserNoob]

Any 3:1 tempera to water ratio works well.

[@CrisAnderson27]

In my experience, tempura is very fragile, and often cracks when it dries. I like it better as it's easier to clean...but the cracking and fragility is frustrating sometimes.

[@LaserNoob]

Yep. Gotta find the sweet spot between fully dry and cracking/peeling.

[@TheSMEAC]

I just wanna hear you keep saying ‘tempura’ 🍤 I will say though too, that far and away tempera paint is the go to for etching items with a diode laser.

[@joeduncan7678]

I just found this video. Great job very detailed. Can I do this same procedure with plexiglass?

[@LaserNoob]

Close to the same. kzbin.info/www/bejne/j3TYfqaQbs2EarM

[@dmplourde17]

Great information. Could you use white tempura paint or do you have to use black?

[@LaserNoob]

Black, to get the white frosted look.

[@Franciscopanchoperez]

this might be a comment on a old post but, I am having a hard time getting the same kind of quality on the engraving on glass using a 50w fiber

[@LaserNoob]

I have never used a fiber laser. So I unfortunately can't help you with that. Sorry!

[@Franciscopanchoperez]

@@LaserNoob thanks for answering. Im used to a 2000watt fiber to cut metals and just got this 50w to play around but glass engrave is not dark/black enough

[@CDCLLC2023]

If you coat one piece of glass with paint and then place a second piece of glass on top of the first piece, you can slowly drag the top piece of glass sideways toward you, keeping it flat until it comes all the way off the bottom piece. The entire top of the bottom piece of glass will now have a completely smooth and even, coating of paint on it.

[@LaserNoob]

Thanks for the tip.

[@thrinfo]

I've tried with my Ortur OLM3 with Liquitex BASICS Acrylic Paint, 400ml (13.5-oz) Bottle, Titanium White, it give you a black color on your glass, I've tried it on Coffee glass and ordinary glass and work fine, I don't have the Blue Laser, I don't know if it exist on Ortur

[@LaserNoob]

The Ortur Laser Master 3 emits a 445nm laser. 445 is a blue diode laser.

[@JoopBastiaannet]

Why dont you use black spray?

[@LaserNoob]

Because I wanted a white frosted look and not black.

[@sharksys]

Thanks so much for the informative video! Have you ever tried a smooth glass cylinder block like you can get at a Hobby Store?

[@LaserNoob]

I have not tried one of those. I've done several jars, glasses and plates though.

[@LaserNoob]

I have not tried it.

[@gregoriusaryanto4816]

i've try engrave on glass using tempera paint for about 6hours. and result pretty good. but got problem when try to clean tempera paint. its not cleaned 100% on some point. how i can totally clean the tempera paint and make glass not look dirty cz of tempera paint?

[@LaserNoob]

I just use warm water and a soft sponge or toothbrush

[@Jamesmyatt1313]

learned lots from you. I have a question, you use poster board under acrylic with tempera but not with glass. is this something you found after experimentation or is it just different with the acrylic? thanks in advance, P.S. FJB LGB

[@LaserNoob]

I don't use it with glass, because I etch glass from the top side. I etch acrylic on the bottom side.

[@jakerazmataz852]

Why wouldn't "fast whitespace scan" be on by default? The rough edges on the jaw of the tempura are really noticeable.

[@LaserNoob]

It is not on by default but stays on once it is enabled.

[@donmusickbestillandknow]

Does thr tempera paint need to be a particular color

[@LaserNoob]

Black

[@kd-CarvingAway]

I'm not sure if you mentioned it but, what was the thickness of the glass? Would any adjustments be need for other thicknesses?

[@LaserNoob]

I never measured the thickness to be honest. It makes no difference if they are thick or thin, only that there is some sort of coating for the laser to hit.

[@PileofBrass]

If the glass is 3mm thick, you set the laser height to the surface of the glass, plus 3mm to get the laser focus on the back of the glass.

[@PedroValejo]

What is the reason to paint the glass first? Won’t the laser just etch right onto the glass?

[@LaserNoob]

No. A blue diode laser will pass through clear glass and acrylics. The paint gives the laser something to hit and etch.

[@playgreat7]

I'm using the ortur laser master 2 5.5W laser. I use the tempera paint as well. what would you recommend me to set the speed and power at for this job? Nice video thanks for explaining!

[@LaserNoob]

Dip or spray your glass in black tempera paint. Then run a speed / power test grid. That's the only sure way to get the right settings for your laser. It will be slow on a 5w, so be prepared for long burn times.

Up

[@stephencampbell9351]

Best way to do Tempera paint is with a AirBrush. Yeah, it's a small investment, but works perfectly and gives you the most control.

Thanks for your opinion.

[@Dancopymus]

Excellent content! I have an xTOOL D1 Pro 10W and, even subscribed to your channel so I don't miss anything. In my opinion, Tempera Ink was the winner here; although, I don't know where to find it because, I live in Brazil. Something similar? Thanks

[@LaserNoob]

I'm glad you like the video. I hope you find it useful. As far as the tempera paint goes, check your local art / craft stores. I hope you find some and can get some glass done!

[@Dancopymus]

Thanks; this paint is a little dense and you have to mix a little water, right?

[@LaserNoob]

I thin it 3 parts paint, 1 part water

[@paulvitti666]

Great tutorial! One question only: What parameters should I choose for a 20w diode laser?

[@LaserNoob]

I do not have a 20w diode, so i can't give you that answer. I always suggest that you do a speed/power test, even if using the same wattage laser I have/use. My 5/10/33/36W lasers may be more or less powerful than the exact same laser someone else has. With that said, I do mention the settings I used on the 10W in the video. Best of luck!

Thanks, So you do the image in threshold? That is what I am trying to figure out thanks for this. Doing Glass ware for the VFW, lots of Letters. Take care

[@LaserNoob]

I"m not doing them as photos. I use svg files, so there is no threshold or jarvis or any of the other choices for photos. If it's a logo with text, you might try to import it into lightburn and then right click and trace. But it needs to be a good quality image to do that.

Hello sir, I’ve tried everything with my laser to get the same results as you but it’s not working I have the yorahome 6550 15 watt diode laser. I painted the acrylic with chalk paint. I tried all kinds of speeds and power but it’s not getting the white finish .

[@LaserNoob]

This video is for glass. Is glass what you're trying to do, or acrylic?

[@francopelaez26]

@@LaserNoob acrylic sir

[@LaserNoob]

Paint your acrylic with black tempera paint. Let it completely dry. Then try around 15% power and 40mm/s. Doing a speed power test grid will get you the settings close.

[@papadopoulosantonis55]

,well i have a question. I am thinking that you get the more white effect cause of the whitness of the tio2 . Its a whitening agent after all. How about using raw tio2 or spaying it before you die it black? I am guessing that the black absorbs light more and thats why it's faster.

[@marxnutz]

Painted side up or down?

[@LaserNoob]

I did these, paint side up.

[@geraldlamothe6091]

Of course the lines are more crisper on the one with the tempera paint because the dpi settings are higher than the one on the galvi...Galvenized paint can come with water also, water and scotch pad.The best way to do these,or even for tiles too...Is to let the tempera or the paint dry for 24hrs before engraving...If you dry it with a heat gun it looks dry but not completely dry...All in all great video!!

[@geraldlamothe6091]

May I add that if you use flat black high heat paint the kind used to paint stove pipes...You will be amazed by the color the etching will leave...It will come out either dark gold or a bronze color. It is very important to let the paint dry 24hrs before etching. Do a test pattern to see all the different shades.

[@richm.1583]

Sir, will this ( Tempera process ) work on acrylic with different settings? Thank You.

[@LaserNoob]

It certainly can. I suggest you run a power/speed test to see what setting will look best on your laser. Lasers vary in power. My 10w may be more or less powerful than your 10w.

Dumb question but could you not run say 3 faster passes, or something of the sort?

Not dumb at all. I don't believe so. Its about getting the coating hot enough to react with the glass.

@@LaserNoob I know that, but higher power/faster passes, creating more "heat exposure" might be beneficial. Figured you maybe could give it a shot or I will hopefully in the next few months when I get mine.
