Firing Schedule:

Please Read: This firing recommendation has been calculated for use with Bullseye Glass of average viscosity with an even thickness of 4 - 6 mm. The chart shown below is also based on the assumption that you are using a top fired kiln, e.g. Nabertherm GF75, GF240 etc. 

Troubleshooting

·        Small kilns such as Skutt Firebox may require hold time at process temperature reducing.

·        Side firing kilns will require more time in the first ramp than top firing kilns.

·        Bubbles in slumping are caused by firing too high or holding too long at process temperature.

·        Remove the shelf when slumping in small kilns.

·        Cracked moulds or cracked glass is caused by firing too fast in the first ramp or cooling too fast.

·        Devitrification on the outside of a slumped piece is caused by firing too high or holding too long at process temperature.
