On a different note, I have Ceramic Raku pieces listed on my Etsy account!  Each piece was bisque fired in a normal electric kiln.  After the glazes are applied, they are placed in an outside kiln.  Once the tempurature reached 1800 degrees, the pieces are pulled out and placed into a bin full of combustible materials.  Once it catches on fire, more combustible materials are placed on top.  A lid is then placed on the bin for oxidation.  After the piece has cooled, it is pulled out and all the metallic colors are reveled.
