Raku firing
Different techniques - what is possible with fire...
01
Raku traditional
After the bisque firing, the pieces are glazed and fired in a gas oven. They are taken out while they are glowing hot and placed in a fire barrel with sawdust. The temperature shock creates cracks in the glaze (craquelé) and the areas without glaze become black-metallic due to the ash and the reduction.
02
Naked
After the bisque firing, the objects are immersed in a slip and glaze and fired in a gas furnace at 1000 °C. Then they are fired with sawdust and dipped in water. The glaze cracks off due to the temperature shock and a silky black and white surface is created.
03
Saggar firing
After the bisque firing, the pieces are processed with oxides and wrapped with leaves, algae, banana skins and covered with a layer of clay. Incredible colorations light up due to the reaction with the different materials.
04
Horsehair - feathers
The pieces should be polished before the raw firing and provided with terra silicata or engobes. At high temperatures taken out of the gas oven while they are red hot and decorated with feathers or horsehair, who burn into the surface and form an individual, unique pattern.
05
Obvara flour soup
In this technique with its origin in Eastern Europe a wood-like surface is created by immersing it in a flour-yeast soup.
06
Copper matte
The pieces are immersed in a copper carbonate mixture and fired in a gas furnace at 950 °C. They are taken out of the furnace red hot and fired with newspaper. Unpredictable metallic effects arise.
