Product Information
Rectangular Concave Dish Mould

Great for creating beautiful contemporary focal pieces, this super mould's slightly concave shape adds interest.

Size: 25cm x 35cm x 1.5cm 

Please note this mould does not fit in the Skutt Firebox 14 or HotStart Pro kilns.  For a smaller rectangular mould, take a look at the Rectangular Plate Mould 8345.

Will this mould fit in my glass kiln?

  • Small kilns may require the process temperature reducing. In the Hobbyfuser reduce the top temperature from 663C to 640C. 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.
