So we added more time to this firing to allow the clay body to mature (maybe mature is the wrong term... not sure what the word I'm looking for is....), and also upped the level of reduction in the first chamber. We are quite pleased with everything out of the first chamber:
In cone 10 news, I made some changes to the two glazes that use our local red clay in them. I added 10% more silica to the dark glaze, and I'm really happy with the results. The crystallization has disappeared for the most part and the glaze now looks like the tests we got out of our little gas kiln.
I also added 5% EPK to the amber ash glaze which kept the glaze from running off of pots onto the shelves and also from pooling in the center of serving bowls:
Christy didn't get as much time to make pots as she would have liked, she did get some nice boxes made though:
As well as decorating several of my larger platters and serving bowls:
All in all the firing was quite good. I feel as though we are finally starting to get all the little idiosyncrasies of our kiln figured out. We are ending up with more and more nice pots out of each firing, and less and less pots that get tossed out into the shard pile.
The only real issue we ran into with this longer firing was the amount of ash that made it into the second chamber. Our celedon ash glaze doesn't do to well with large amount of ash on it. It tends to foam up. This can be interesting in small quantities, but in large amount you end up with this:
We'll post more pictures as we work toward getting our place all ready for the Fall Art Tour. This was a really good event last year for us, and we are looking forward to seeing everybody again this year.

Your pots are gorgeous! I hope you still have some good ones around when I get there in December; I'll give myself a Christmas present!
