Packed Kiln

This is my kiln being packed for bisque firing. I pack it as fully as I can for better fuel efficiency, within the limitation of needing to allow adequate heat circulation around the pottery. My work is generally fairly fine- usually about 2-3 mm thick, so I can stack three or four pieces on top of each other without reducing heat penetration too much. If I was working with 1 cm or more thick walls I wouldn’t get away with this kind of stacking. A glaze kiln can’t fit as much because individual pieces can’t touch each other or the glaze fuses them together. My small pieces are good for filling the gaps left around the larger pieces in a glaze firing.
