Pocket Vase Problems

- Never fire directly on the floor of the kiln. The inability for the air to circulate below the work makes it exceptionally difficult to heat the glass evenly.
- Pocket vases are problematic because the material holding the pocket open insulates some of the glass below out. The glass that sticks out heats quickly – the glass under the fiber paper (or whatever you use to hold the pocket open) heats slowly. The result is thermal shock.
We used to do pocket vases in one of our classes but stopped — they just thermal shock too easily.
