Adding a personal design to glass and ceramics is very easy and something fun you can do with creative kids. You can pick up plain glass and ceramic housewares secondhand, and I find some good stuff in the clearance section of places such as Home Sense and Winners.
To make your designs, you can freehand with the pens, or use masking tape to contain your ink.You can also use transparent adhesive masking (from Lee Valley) to create a stencil as well.Peel the mask away carefully. This is easiest to do when the design is still wet.Once the design has dried you can use a razor blade or craft knife to carefully scrape away any ink that has bled through the masking.If you’re not happy with your design, you can always use a scrubby sponge to scrape it off and begin again. Leave your final design to cure for 24 hours, then bake your glass or ceramics in the oven according to the instructions on the ink.That’s all there is to it. Have fun!
