Number 4 - 12.1x10.3x1.9cm - Opening: 9x7.5cm

This flat casting mould will result in a decorative finished glass object or a component to be further used in fused or cast work.

The recommended firing chart will lead to a smooth piece of glass with a glossy surface. The finished piece will shrink somewhat, depending on the amount of glass used. Some coldworking on the edges with a diamond pad may be necessary.

By lowering the temperature to a sinter firing (approx. 720°C) the piece will shrink less and have a rougher ‘Sugary’ look like pâte-de-verre.
