The characteristic feature of raku firing is that works are heated in a kiln to approx. 1000°C in a short time and then taken out of the kiln with tongs. The enormous thermal shock causes cracks in the glaze typical of the raku technique. Gerald Pfaffl and the team of the ceramics studio demonstrate the raku firing technique in the university courtyard at Oskar-Kokoschka-Platz.
