    Hey Bill, I am always amazed with the results you get consistently from glass. I havent played with glass yet, but will at some point when some time presents itself. But in the meantime I keep watching what others are experiencing, both on this forum and folks who do it locally, and every time the results I see are so inferior to sandblasting I just dont understand what is going on. Like you and Dan, I know a very few who seem to be able to do it consistently well, but most flail at it and get pretty disappointing and often highly variable results. And these are people who I know approach something like this methodically and carefully, bracketing around techniques looking for the sweet spot that gives them good results, and they have good luck with every material they play with. Except of course, glass! I also noted that when I could compared well lasered glass against sandblasted glass the sandblasting is clearly better. Have you had a chance to compare your engraving on glass against similar efforts with abrasives? Just curious. It also seemed that the abrasive work I have seen was much faster than lasering glass. Any thoughts on that?

    It is fascinating to follow. Someday, I will be so fascinated I will try it myself....drawn like a mouse to the gaping jaws of a snake I suppose. <grin>
    Thanks for sharing all your techniques in that earlier post BTW. I have saved that for when I hear the siren call of glass engraving.

    Sorry it took so long to get back you, busy,busy,busy... I do mostly photographs on glass, it's my speciality, and I have never seen a piece of sandblasted glass that can even come close to the detail I can achieve with the laser. A sand blast mask will not hold a stochastic screen fine enough for really high detail. Sand is great for text & line art, but with proper image correction for detailed work the blast masking falls way short. There is lots of my work posted here but I have yet to see anything close to the detail done with a sandblaster. If anyone can show me, I would be fascinated to see how it's done.

    I Have to think outside the box.. I don't fit in it anymore


    Experience is a wonderful thing.
    It enables you to recognize a mistake when you make it again.


    Every silver lining has a cloud around it

    Hi Bill,
    I bow to your expertise in photographs I will freely confess that you and a couple of others, do outstanding work with photos on lasers. I do however think that for text, logos etc, there is nothing like sandblasting for a perfect finish every time. Almost never a reject and customers love the resulting depth and crispness.

    I believe that engraving depends of a glass quality. Every year we get to engrave the same glass plaque that has those magic letter syndrome. I have tried different dpi, speed, power and letters keep behaving like ninjas. And this year, same plaque but it was good after first try! all of them! I do not know how did this happened because I have settings in software for this tippical glass. Well, you learn very day something new.

    I just installed a sand blaster myself after having my 80w laser for many years, and I tried some window glass in my laser, and just a few minutes ago I tried the same image in the blaster, well the blasted looks the best.

    The laser looks watered down, or not a white as the blasted does.

    I like the idea of using the laser for flat glass, no stencil to cut and position, no having to put on the gloves, and not having to peel the stencil off.
    I will keep both though.

    I don't do a lot of glass, but for what it is worth this seems to be a pretty good article:
