Create a simple piece of artwork or a functional item of dinnerware. This is a very special mould which makes a medium size but fairly deep bowl.
Try fusing identical pieces from two contrasting colours. The steep angle of this mould will reveal the bottom colour around the edges.
Size: 29cm diameter and 8cm deep. Fits in a HotStart Pro kiln. For a smaller bowl try mould 8343.
Bullseye Code: 8975
Please Read: The steep angle of the mould may result in an uneven slumping. Reposition the slumped piece and fire a second time. Use a very low slumping temperature with a long soak.
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.
*If possible, visually confirm slump.
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.
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.
