Handbuilt burneshed pieces with terra sigillata, raku fired. Stiudio and gallery in Velden / Austria. All actual pieces are coilbuilt in different technics from grogged German stoneware clay. They are burnished when leatherhard and covered with thin layers of terra sigillata. That is a very fine shiny slip also used in ancient history in different cultures which I produce from special clay bodies. After a first biscuit firing again a second time layers of terra sigillata are put on followed by a second firing.

Then the pieces are covered with a slip and sometimes glazed. They are fired in a gas kiln with following reduction in sawdust. With influence of water the slip crackles away like an egg-shell, the burnished piece appears again. At least, a thin layer of beewax is put on the surface. Vessels which should hold liquid are made dense.

I call this technique ? VERLORENE GLASUR? ( Lost glaze).
