Firing Schedule:

Please Read: This firing recommendation has been calculated using Bullseye Glass with a thickness of 6 mm in a Paragon GL24 kiln, and is courtesy of Bullseye Glass Co. 

Segment Rate (C/hr) Temp. Hold
1 167C 657C :05
2 999 482C 1:00
3 56C 371C :00


  • Small kilns may require the process temperature reducing. In the Hobbyfuser and HotStart Pro, reduce the top temperature from 657C to 634C. In the Firebox 14, reduce the top temperature from 657C to 614C. All kilns vary, as does glass viscosity. Testing is necessary.
  • Remove the shelf when slumping in small kilns.
  • Side firing kilns may 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.
  • 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.

Please note that all our moulds are hand-made and therefore the dimensions may vary slightly from those shown. Mould manufacturers allow a tolerance of up to 2cm. We strongly recommend cutting the glass to the size measured from the actual mould rather than relying solely on the dimensions shown.

All our moulds are designed for multiple use and with care should last for many firings.

Customer Questions
Could I make two spoon rests at the same time using this or am I better to buy the smaller ‘spoon rest’ mould? Thank you.

If you have at least 2 cm gap between your glass you can slump two at a time on this mould. Although the shape of this mould is slightly different to the spoon rest, either will work
