Give it a go! Works well with the 13.5cm clear pre-cut circle. 


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 663C 1:30
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 663C to 640C. In the Firebox 14, reduce the top temperature from 663C to 620C. 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.

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