It was fired in place. In this image from the website http://m.youtube.com/watch?v=LM-_BfifybI. It was made by Åke and Eva Nobling of Lokatta Keramik (http://www.noblingceramics.com) The fuel was wood, and the kiln was the thin white material at the bottom, which has fallen away from the "self firing" sculpture.
