I have always been looking for ways to put images on glass, sandblasting, decals, enamels etc. There is a product, Glassline, that is for glass and ceramics. It is not design for paint as such, but more for line drawing. It fires from 1300 to 1500 degrees. You can use it in a airbrush to get nice even coating and that is what I did for these projects. I was expecting for fail big time when I first tried, but to my surprise the laser actually fused the paint to the glass with not fumes or without the glass chipping or breaking. I took a scrub brush to the image and it didn’t budge. As a habit with working with Glassline I always fire a clear coat of powder to finish my project. It also helps if you pre-fire you blank so that the surface is as smooth as posible.
The first image is of a line drawing. Airbrushed with black Glassline and printed the image. (Sorry for the blury image) The setting were for Engrave, Full Power, speed at 500. Line density was at 195. The dot matrix is a little tricky. Too much and it burns the paint off instead of fusing it. I found that this setting needs to be adjust to the image.
The next project was with the help of Paintshop (corel version of photoshop). I took an image of a table top and layer a doilie that my mother had done over it. Air brush brown paint and printed it and cleaned off the loose paint. Then I airbrush black paint over where the lettering was and printed that.
Simple images work the best with any kind of text. This was just that.
