Karin Putsch-Grassi studied ceramics at the Art Institute of Florence and later at Goldsmith’s College London. Her main interest was in the firing process, and she immediately started to build and fire different kinds of kilns: low fire wood kilns, gas kilns, raku and soda fired kilns made of firebricks and ceramic fibre. In 2009 she and her husband built their first kiln of empty wine bottles; 500 positioned horizontally in rows and stuck together with sandy soil, to a height of 2.20m. The main difficulties are how to hold the complete structure together, and not to exceed the melting point of the glass bottles. The result, as we will see, is stunning!
