For Bullseye and System 96
For Bullseye and System 96 the firing schedules on this site (under the “Tools” menu above) will work fine. A proper slumping schedule should never be hot enough to cause glass to flow and distort a kiln carving. Stretching the design can be an issue with a deep slump.
The most important thing to watch for when slumping kiln carved glass is thermal shock since kiln carvings tend to severe thickness changes.
