The purpose of this mould is to create a clean and sharp texture in your glass. Ideal for serial work of tiles etc. If you like the fish texture to appear on a slumped bowl, use this texture mould for your first firing cycles, at or close to a fusing temperature. Then slump the glass in a subsequent firing on a shallow slumper, e.g. Flat Slumper - Medium - 28x28x2.5cm - Fusing Mould 958.372.
By cutting the glass smaller than the mould size, you can select specific areas of the mould for a series of slightly varying results. Instead of cutting the glass square try a circular piece instead. Pre-fuse a layer of a light transparent glass onto clear to obtain a colour shading as a result of the varying thickness produced by the texture.
Recommended Firing Chart
The chart shown below is also based on the assumption that you are using a top fired kiln, e.g. Paragon GL22, GL24, BVD Flat bed kilns etc.
Following this 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 'sugary' look similar to pâte-de-verre.
