I fired last week. When I’m done glazing, but before I load the soda kiln, I sit down and roll hundreds of wads for the bottom of my pieces. It always takes a ridiculously long amount of time. Time when I’m feeling a bit anxious about getting things done on schedule. When I was rolling my wads for this last kiln, it was a sunny day, and the morning sun was hitting them in the most beautiful way. I took this picture to share with all of you. My happy spin on a less than fun job.
Wadding Recipe for the soda kiln (pretty standard) (by volume):
- 1 part EPK
- 1 part alumina hydrate
- medium grog to taste (not really, but you know what I mean…)
I roll my wads ahead of time and put them in a plastic container (the ones from the local Thai take-out place are the best). Then I glue them to the bottoms of pots before loading (Elmer’s glue). Breaking up the wadding into steps keeps my hands cleaner and helps me avoid the problem of getting wadding where it doesn’t belong.
- 1.75 lbs. of soda ash
- 2.25 lbs. of soda bicarb
- 4 lbs. of whiting
Mixed together with 1/4 of a 5 gallon bucket of wood chips. Mix together well, then add enough water (while mixing) to the consistency of oatmeal cookie dough. I add it on an piece of angle iron through the ports on the front of the kiln when c. 9 is soft. (More on this in a future post.)
