Product Information
Large Classic Mould  

Create elegant bowls with this large circular mould. It has a flat base so you can make a beautiful centrepiece that is also a functional object.

This is the biggest circle mould we do - 40cm across and 10cm in depth. The flat base diameter is 14.5cm (Please note this will not fit in the Hotstart, Firebox 14 and Paragon Fusion 16).

With larger moulds such as this one, your glass blank can overhang the mould by up to 1cm without any problems. Wider than this and the blank may catch on the side of the mould during slumping.

Will this mould fit in my glass kiln?

If you need a smaller mould for your kiln, this popular style is also available in Small and Medium sizes.

  • 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.

I recommend this firing schedule. I was firing a thinner piece uneven thickness so dropped the first ramp to 185 ph and the second to 280 ph. This mould is not as scary to use as it looks have fun!
