Just wanted to thank everybody who responded to me and tell you that my
latest firing was just about right. 6.5 hours to cone 7, with an
overnight preheat. Temperature and reduction pretty much even
throughout. Pretty much the only changes I made were I took away the
bag wall and moved the bottom shelf back towards the back wall. And I
took out the extra bricks I had put underneath the load to baffle the
flames. I'm sure I can tweak it a bit and make it more perfect but now I
know what I might want to do.
Bill Schran, I can't thank you enough for telling me that if you pull
the damper out the heat goes to the bottom. I'm so glad you caught that
in my first post. Now my kiln fires right side up. Turning down the gas
pressure or pulling out the damper both do exactly the opposite of what
they used to do!
The next step, Mel, is to try preheating with 1/2" instead of 1" of
pressure to save fuel and protect the bricks.
