The basis of the tiles is a combination of different clays and loam. Mixed in the workshop with quartz sand and fireclay, the mass is then pressed into the tile form and precisely reshaped by hand. Through a silkscreen process the basic material now acquires form. The glaze impresses rhythmical symbols in the tiles. Each of the raku tiles is worked by hand 36 times before it is used and laid in place. Unlike with industrial methods the handcrafted production allows a genuine response to individual requirements.
