I unloaded the first firing in my new kiln! It fired like a Rolls Royce. The Big Bertha burners are incredibly powerful, and run smoooth! They are everything Tom says they are. The kiln was very responsive to any subtle changes made during the firing, which is key to having a kiln that works FOR you! I'm in the process of preparing for another bisque of my larger pieces, while glazing some smaller works for a cone 6 firing. Stay tuned for some pics of the process of loading my large lion dogs into the kiln. Even the thought of it makes me nervous!
