Two wood-fired pieces, both approx. 5 - 6" tall (fired in the experimental kiln "Mini-Me-Agama"). Soda was also sprayed into the kiln at approx. 2300 degrees F.
The kiln was built by the advanced class: Ceramic Sculpture, Tools & Techniques. However, all students had the opportunity to fire work in this kiln.
The small wood/salt/soda kiln was built with refractory cement and recycled brick (total cost = $150). The first couple of firings were a bit rocky, but eventually students consistently hit cone 11 in an 8-10 hour firing, weather permitting (and sometimes with the help of a propane burner at the very end).
Both of these pieces were not glazed on the outside -- the shiny surface was due to the soda we introduced into the firing.
