While wearing safety glasses, score glass with the glass cutter and break using breaking pliers, or use mosaic nippers to cut off small pieces of glass.
Cut a piece of thin-fire shelf paper to fit your kiln shelf.
Working on the shelf-paper (on the shelf) stack the glass until it is approximately ¼" thick (2 layers that are 1/8" thick, 4 layers that are 1/16" thick, etc.), placing any black or dark colored pieces on the bottom, and a layer of clear glass at the same COE on the top. Create small "stones" or cabochons approximately ½" to 1" in size.
Place the shelf into the room temperature kiln and begin the firing process. To fire glass in a kiln ramp the temperature up at about 20 degrees per minute until you reach approximately 1500-1600 degrees F. Hold this temperature for about 5 minutes, until the glass is smooth on the surface and the edges are rounded over.
Flash vent the kiln to stop the firing process. To do this open the kiln for a count of about 5 seconds, then close, let the temperature stabilize for a moment, and open again for approximately 5 seconds. Repeat this process until the temperature reads approximately 1100 degrees F. Then close the kiln and turn off the power supply to let the kiln finish cooling. Do not open the kiln during this time until it is below 200 degrees F.
Once cooled, remove the cabochons from the kiln and rinse clean. If there are any sharp points around the edges they can be removed using a glass grinder or an abrasive stone.
Using a portion of your PMC+ clay, create a pendant by either rolling a coil and firmly encircling the cabochon, or by rolling out a section of clay and folding it to create a setting around the cabochon. The creative possibilities are nearly endless. Use the PMC+ Paste to repair any cracks and reinforce any joints.
Add any detailing or other design elements desired.
Let clay dry thoroughly and file to clean up edges. Use a small amount of rubbing alcohol on a cotton swab to clean the surface of the cabochon.
Fire in your kiln by bringing the temperature up about 20 degrees F per minute until you reach 1650 degrees F. Hold at this temperature for about 10 minutes, then flash vent to 1100 degrees F as described above. Close the kiln and turn off the power supply to allow projects to cool. Do not open the kiln again until it is below 200 degrees F.
Polish the project with a wire bristle brush to remove any residue left by firing. You may complete the polishing process by placing the pendant into a tumbler with stainless steel shot to produce an even, high gloss finish.
Note: Firing schedules may vary. Delphi recommends a lower firing temperature when glass is included in the PMC project, as the silver particles in contact with the glass may cause a color shift or "ambering" around the edges. We encourage you to experiment with this schedule while keeping in mind that the longer the PMC+ Silver is fired, the denser the metal becomes, ensuring strength.
