Product Information
Rectangular Slumper.

The simplicity of this mould guarantees an elegant piece of glass, be it artwork or a functional piece.  A very good shape especially for starters, salads or desserts.

Instead of cutting the glass to match the mould shape, try an oval or a narrower piece of glass.

Size: 38 x 19cm and 4cm deep.

Will this mould fit in my glass kiln?

If you are looking for a smaller rectangular mould, try the Rectangular Server mould.

 

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 649C :05
2 999 482C 1:00
3 56C 371C :00
4 999 21C :00

Troubleshooting

  • Small kilns may require the process temperature reducing. In the Hobbyfuser and HotStart Pro, reduce the top temperature from 649C to 626C. In the Firebox 14, reduce the top temperature from 649C to 606C. 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. 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.

This is a great mould in that it can be used to create functional ware, but the gradual angles mean that you can create landscape or other designs which are not disturbed by the slumping. The 2:1 format is good for designs and the 36 cm length is just less than a 40 cm glass sheet making for efficient use of glass. The only downside is that it is only just too large to use in my skutt 14 kiln!
