Product Information

These deep curve moulds are perfect to slump your glass projects, adding shape and depth to your design. Ideal for home decor, gifts and beautiful display pieces.

The depth of these moulds ensures that your curved glass will be able to stand freely after firing.

Primer should always be applied to the mould before slumping, we recommend Boron Nitride Spray with Stainless Steel Moulds.

Product dimensions:

  • Small -  15.5cm x 12.5cm (7cm depth)
  • Medium - 21.5cm x 12.5cm (9.5cm depth)
  • Large - 27cm x 12.5cm (11.5cm depth)

Please note: Make sure to remove any protective film or stickers from the moulds before use.

Firing Schedule:

This firing recommendation has been calculated using Bullseye Glass with a thickness of 6 mm in a Paragon GL24 kiln. 

Segment Rate (C/hr) Temp. Hold
1 167C 649C :20
2 999 482C 1:00
3 56C 371C :00

Troubleshooting:

  • Small kilns may require the process temperature reducing. In the Hobbyfuser reduce the top temperature from 649C to 626C. 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.

We recommend using our Boron Nitride Spray with this mould for an easy release.

Each mould may vary slightly due to the manufacturing process so we would always recommend cutting the glass to the size measured from the actual mould rather than relying solely on the dimensions shown.

The large curve mould has just arrived and I am a bit daunted by its size. I'm not sure how to go about using it. After the first firing of the glass piece to be bent do I just balance it on the curve and keep my fingers crossed it doesn't slide off during the firing? Would appreciate help,.can't see anything in the help sheets or videos.
WARM GLASS REPLY: Yes balance it on the top. Make sure you prime the mould with Boron Nitride spray first.

Much larger than I had imagined in my head but that just means I can use it for lots of different sized products. Used with the Tygris release spray and everything worked perfectly. Only used it once so far but hoping for similar results every time and definitely going to invest in another.
