    Any suggestion on what is the best way to colour fill glass etchings

    Ie.. colour fill , what paints or resins , How to get that nice white etch
    What would last a long time for quality purposes

    With proper settings you should get a nice white etch, less power and more speed is best.

    If you do need to paint fill, etch through a mask like paper transfer tape, and paint with special glass paint like Liquitex Acrylic.

    Hi Shadow,
    I don't have much experience with the etching process but I know that it's better etched on the reverse side in reverse, then colour filled.
    I have tried "Rub N Buff" but had limited success and didn't like the finish very much. The mirrors I engrave on the back face are painted with a good quality enamel paint which seems to do the job pretty well so far but all the people on the forums talking about this method seem to like the Acrylic paints for luster, colour and finish.

    THX GUYS

    Thx bisjoe

    I give that a try
    Like most people you look at more power to get a whiter look nut you dont think less power LOL

    Thx mononueron
    Im trying to do high res photo like engraving so color fill with acrylic is a little harder
    Im going to try to get some clear film to place over the work before i start to reduce the overflow of the paint

    It will take me awhile to work out which way is best but that can be half the fun with trial and error

    Many thx

    I use all the power available on my 30 watt laser and run at about 3.5 inches/sec just to burn through the mirror backing. It takes ages to do a 12 inch square mirror (like 3 hours) but it turns out pretty well. I just go off and do something else like post on this forum. I have to set my dots per inch to 340 and above so as not to have any lines uncut which leave a shiny line on the finished product.

    It's a home made one with a ULS 30 watt RF laser adapted to it and running Linkmotion software.

    Try rayzist.com They specialize in glass etching supplies although it is usually done with a sandblaster. Lasers can etch an image onto glass but can not get the image deep enough to fill with color. One division of my company does glass etching with color filling and we never use a laser to put an image onto glass... sandblast only.

    Smile THX MATE

    Thx mate ill give it some thought im looking at doing some high detail work so i dont believe sandblasting will get the detail i want but ill have a look at it
    Im not just looking at glass but and have a few other idea to try but all will require some high detail work but i would like to color the glass after engraving
    Might have to mix it with other mediums ie resin, glues, ...etc ...to bring out the colors

    Still not sure which way im gonna go with it But i would like to do something with some high detail artwork
    Bit of a learning curve

    I have done photos in mirror by rastering them and then spray painting a lacquer base flat black on the back of the mirror, they turn out great. I also use KRYLON X Metals paint for some light boxes I build, because it lets light pass through.
