Things You'll Need:
- Glass
- Glass fusing kiln
-
Step 1
Stack COE compatible glass in opposite direction to create round cabs.Cut two ½ x ½ inch square pieces of COE compatible glass. Stack the glass and place it on the shelf of a glass fusing kiln . For round pieces, the pieces should be sitting in the opposite direction so they fuse into a circle. For square cabs, the glass should be placed so it is sitting square.
-
Step 2
Repeat until you have made desired number of cabochons in the size and shape you require.
-
Step 3
Small glass fusing kiln.Place the prepared shelf in the glass fusing kiln.
-
Step 4
Glass cabs in kiln.Fire using the following schedule as a guide:
Ramp ºF/Hr Target temperature Hold for
1 Full 1630 5
Allow the cabochons to stay in the kiln until they have reached room temperature. Note that since you are making small cabs, no annealing ramp is required when firing the glass. If you make larger glass cabs, you will need to build in an annealing ramp. -
Step 5
The glass cabochons can be used as is or drilled and made into beads. To drill beads, prepare a bath to drill the cabs. Drill slowly and carefully. If you do not know how to drill glass see our eHow How to Drill Glass at http://www.ehow.com/how_4803518_drill-glass.html of click the link in the resources section of this tutorial. Once drilled, place the cabs in the kiln for a fire polishing using the following schedule as a guide:
Ramp ºF/Hr Target temperature Hold for
1 350 1410 10
2 Full 960 15
3 150 700 0
