I hope to do two more firings this year in the new kiln before it gets too hot and dry. This means I need to get busy creating enough work to fill the kiln twice! However, before I do the next firing I will need to do some modifications to the kiln. I am hoping these modifications will allow the kiln to fire more evenly. With the current design only the pots and shelves can deflect the flames and heat upwards. So during the last firing everything in the middle of the kiln fired well due to the flame being pulled directly across the kiln chamber (see below).
I am planning to build a bag wall inside the kiln to help deflect the flame upwards. The bricks will be laid in a checker board fashion, to leave holes that flames can pass through. This is so that all the heat is not directed up and then over the pots in the chamber, creating new problems (see below).
