Stainless Steel Fold Mould

Create your own free-standing picture with this exciting stainless steel mould. This clever design ensures that your slumped glass will be able to stand freely after firing without the need for display stands, keeping all the focus on you glass project!

This mould works best with 3mm glass, simply place your glass over the mould and fire to a slump mould.

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

Product dimensions: 12.5cm wide x 14cm length x 6cm depth (lip is 1.5cm)

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 3mm. 

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.
