Firing and Finishing

A weekend of work ready for firing.

Loading the kiln

The kiln heats up. A full fuse occurs around 1550 degrees. Although in this big kiln, it seem to fuse at about 1450 degrees.

Fusing complete. The pendants appear to be pools of red hot liquid at full fuse. The original color of the glass will come back as they cool. When you reach the fused look you want, it's important to flash cool the kiln by opening it slightly. You want to get the kiln temp down to around 950 degrees. In this range, the glass anneals (controlled cooling that allows the inside of the glass to cool at a similar rate to the outside of the glass).

The next step in finishing the pendants is attaching the pendant bail. I use a small file to lightly file down any rough spots or edges and then "rough up" the area where I plan to put the bail. I then apply a small dab of E6000 to the bail and press it down on the back of the piece. I let a little bit seep over the edges and then use a finger to clean up any excess glue. It's important to let the freshly glued bail sit for about 24 hours before wearing.
