The Pyramid Kiln excels because of its simplicity and efficiency. It offers enormous prospects for experimenting. It can be fired with wood or propane gas, in reduction or oxidising, for RAKU, biscuit or full glaze firing, either fully loaded or for a quick firing with just one pot.
It has two handles on the outside, so moving the kiln is very easy. The 135 Lt top weighs 45Kg , one kiln top can swapped between a wood firing base and a gas firing hearth!
Because of its pyramid shape, the heat in the kiln is deflected downwards before leaving via the flue. This results in a very fast temperature increase while using little energy. This design and good insulation allows for example, about 5 - 7 Raku firings to a temperature of 1050°C can be obtained from one 11 kg propane gas holder.
The first firing will take about 75 minutes, and subsequent firings 60 minutes to reach that temperature. Firing the kiln with wood is even quicker. After firing the kiln with dry wood for about one hour, one can reach temperature andunload every 30 minutes with a minimal amount of wood.
The sloping door design means that it always locks the kiln tight, because of its weight. But it can still be opened quickly and easily, or just open a crack to check on themelting of the glaze, which is very useful for RAKU firing.
Moreover, because this kiln's door is on the side insteadof at the top there's less risk of burnt eyelashes and eyebrows and thus SAFER. Operating the wood fired kiln provides full involvement with the firing process. Sitting quietly beside your kiln and occasionally chopping some woodwhile looking at the flames and the glow of the fire
Opening the door and looking into the kiln to see if the glazeis already fusing and experiencing how beautiful the transparent orange colours are and how hot it is at about 1000°C. A larger involvement with the firing process can hardly be imagined.
Firing the wood kiln is easy. Itseems that the kiln is firing itself. It appears that everybody develops their own ideas about the fire build-up and the ways of reducing, so that firing the kiln becomes a very personal experience.
