While adjunct potter, John Simmons is stoking up the kiln, I'm taking some downtime and downloaded a bunch of pictures from the last couple of days deco-rotation highlights. But I wanted to quickly share with you new strategy I'm employing in this firing, soda ash rocks!
I'm not sure what to call these things, but Emily Murphy uses them to salt (soda) her kiln. But basically they're a mixture of soda ash, baking soda, and whiting (calcium carb) which is mixed with lots of sawdust (but no dirt). Here's a link that explains the whole deal. Check it out.
Ironically I've been having trouble getting good sodium penetration in the upper part of the kiln. Hopefully these will take the place of salt cups that I've used in the past.
Here is a contextural shot showing the balls in place.
I'll try to get around to posting more deco highlights on the cooling days as well as some before and after! Follow the firing on my twitter feed, where I will make updates throughout the day.
