This kiln has a total volume of 550 cubic feet, when factoring in bag walls, and fireboxes. It has 250 cubic feet of shelving area in the chambers. The main firebox can take wood up to 6 ft long and burns both hard and softwood, depending on the cycle. The pots have been bisque fired "first" in a gas kiln, allowing for a faster start during the wood firing.
The kiln was designed so there is plenty of room to maneuver in the chambers when loading. Each firing holds about 1500 pots, including a dozen or more large planters and urns. One of the reasons Robert built this kiln was to enable him to fire large pots.
Six Week Firing Cycle
Glazing a kiln load takes about 14 days plus another 12 days to wad and load the pots. The actual firing time is 62 hours then 5 days of cooling before unloading. Unloading the kiln, grading then pricing pots adds another 18 days. This kiln is fired twice a year, usually in the months of June and September.
