You can make some interesting jewelry using fused glass methods, and learning how to cut a hole in glass is a good technique for attached jump rings, bails, and other findings to the glass components you make. For example, pictured are some glass cabs I made, which I call "Opal Glass," and then I cut holes at the top of some of them and used wire to create bails.
You will need the following tools and supplies:
Diamond core bits
Thin piece of wood
Shallow plastic dish (Left over frozen inner dishes work well.)
Protective eye wear
Pair of hemostats
Note about Equipment: A drill press can be purchased where most power tools can be found and range in price from $50 to $100. I purchased a set of diamond core bits (which range in size) is available from Rio Grande.
Safety Note: As with any power tool, be careful and use your common sense. Have hair tied back and wear protective eye and ear wear. Do not put your fingers directly under the drill bit.
