Wood Chamber: Loaded

There were several comments about the bottom of this chamber being empty, and, of course, Michael Kline had it figured right. I’ve only fired this kiln 4 times and I have struggled to get heat to the bottom. It is a very tall chamber (6′) and I worry that I’ll never solve it. This is the first two chamber kiln I’ve built and I still have lots to learn.
I did open the bag wall and lower the packing place for firing #3 (the ‘Kelvin’ firing’*), but all it did was drop all the ash on the bottom shelf and it ended up even colder. I would be happy to hear suggestions if any of you have any ideas.
Today I’m getting out to the studio early and will begin to load the salt chamber.
(* During the night time shift, Paul and Bill managed to switch the pyro reading from Fahrenheit to Kelvin! It was more than a little confusing until we figured it out.)
