2. BREAK THE GLASS
Trace the lines of your design on the glass, using a special pencil-shaped scoring tool. The blade does not cut the glass, but scores it, allowing the pieces to be broken more easily into desired shapes.
Use several specialty pliers to break the glass into shapes, placing the waffle grid underneath to catch the broken pieces. This step was the hardest to learn. I broke many sheets of glass before doing it right!
3. GRIND THE GLASS EDGES
Once the pieces are cut, use a special glass water grinder to grind the edges of every piece of glass.
Grind the sides down to prep for foil adhesion.
4. FOIL THE GLASS EDGES
Make sure all pieces are dry.
Apply a copper foil tape and wrap the edges of each piece with the foil.
Use a tool, like the end of a paintbrush, to “burnish” the tape around the pieces of glass. The copper foil gives the metal solder something to adhere to in the next step.
