After the success of Blog Number 8, "9 Easy Steps to Silk-screen Printing on Glass", I've decided to post a more detailed step-by-step posting titled "Shortcuts for Silk-screen Printing on Glass." I will specifically talking about how I cut and print on glass, using visuals from a work in progress.
With all my work I first design the work and print it full size to use as a "cartoon" to cut the glass to fit. Cartoon is basically the paper printout pattern of the design. Like a large jigsaw puzzle, all the glass should fit together as close as possible on top of the cartoon.
To cut glass precisely, I use a glass cutter and flat nose pliers to grind the edge of the glass. I also use a ring saw to cut intricate concave shapes only when needed. I skip using any wet glass grinders, they waste time and slow the process down.
When making a silk-screen save the original acetate image. I tape this acetate onto the silk-screen board, and tape the cut glass down on top. Place your glass in the exact positioning you need. I add tape to the back of other pieces of glass and tape them down as well.
Once I have the glass pieces under the screen, I use the best water based enamel on earth, produced by ColorLine (you guessed it, I love this stuff). I only add the enamel above the glass pieces, and not in areas where their is no glass underneath, so when I "pull the enamel" with the squeegee, I also save on materials. To see the steps for silk-screening please visit Blog 8.
Place as many pieces of glass on the kiln shelf as you can, then bake. ColorLine enamels bake at 1300 degrees in a "polish firing" where only the surface layer of enamel is permanently baked onto the glass. This kiln fired enamel method dates to Medieval times.
