The smooth inside of this mould will give you a shiny glass surface with hardly any need for coldworking. Coldworking of one side is an option to reveal the inside life of the pyramid.

You can vary the glass quantity to alter the size of the final piece. For a full pyramid you need approx. 2 kg of glass. For high clarity use billets but you can also use sheet glass, frit or rods for different results. 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.
