The pre-programmed modes automatically turn the kiln up when it is safe to fire the pieces quickly, and down when the clay is at a point where it should be fired slowly. Once kiln shelves are selected and used, regular maintenance is required (kiln wash and reversing shelves). For longer runs you will have to increase the size of the hook up wire (must be copper). Intuitively the slab lining seen in Ancestral Pueblo B/W kilns serves to contain and reflect some of the heat of firing back into the kiln, resulting in effectively higher temperatures given the same amount of fuel. In reduction firing, oxygen is prevented from interacting with the glazes during glaze maturation. * Use kiln wash on top of all kiln shelves. d) select MEDIUM firing option Often, as the kiln ages, the peephole widens and the plugs are too loose to stay in. * The worst thing you can do is fire low fire clay or glazes at high fire.

Mel Jacobson recommended using a diluted bleach to clean the coating off the new elements, then dip the prepared elements in ITC 213 and let then dry. The trick is to reduce the amount of oxygen entering the kiln while the burners are still lit. 5) Door should have a lock with a sign making sure it is known to be a restricted area. Therefore, the location of the room vent and the inlet grid needs to be carefully selected to insure the proper air path. * Use half kiln shelves - they are lighter and will give you more flexibility loading the kiln more efficiently. If budget permits, I recommend that you order the kiln with APM elements although standard elements will be satisfactory. Firing the two kilns on the same day made me realize that the firing process developed for replicating Black-on-white pottery is not appropriate for firing in oxidation. As per our discussion, see below a detailed report reflecting the areas where you requested assistance. When it does, set the timer on the Kiln Sitter/Timer to 2 hours. 2.
