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.

Troubleshooting:

  • Small kilns may require the process temperature reducing. 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.

  • To prevent the glass pulling in at the edges when it slumps into the top of the mould, make sure your glass is slightly wider (no more than 5mm) than the edge of the mould. This will stop the glass pulling in at the sides.

Warm GlassUse two contrasting opaque colours for the top and bottom layer to draw attention to contour lines around the edge.

 

All our moulds are designed for multiple use and with care should last for many firings.

I much prefer deeper moulds like this to the very shallow that you often get, and I find this is a handy size, with enough surface to be creative. I always use primo primer and rarely recoat - I only use tekta or trans as a base and I think that helps. My mould does measure fractionally smaller than the listed measurements, but I always cut pieces slightly larger than the mould so once slumped they fill it to the edges.

This mould is smaller than the indicated dimensions 16.5X16.5 cm. The slumped glass size is 16X16 cm.
