Sorry for the delay getting these pictures up. Over all we had a good firing. As always there are things to improve. First thing to improve is probably our clay body. We keep getting small cracks on our pots in the front of the kiln, and this firing a couple of the larger platters slumped slightly. Not much but enough that what used to be a nice platter now looks like it was poorly made. Our clay is a mix of kaolin, and ball clay with about 8% neph sy, silica, and grog. We were aiming for a clay that flashed well.
Faceted box from this last firing.
I am pleased with the way our clay body flashes. However the cracking, and slumping aren't so pleasant. Mind you we didn't lose that many pots from this last firing due to clay issues. Still room for improvement though. We'll probably start by taking out 10-20% of the ball clay and substituting some Hawthorne bond clay (fireclay) hopefully we won't lose too much of the flashing we like so much.
Our new glazes were a bit of a mixed bag as well. The whites came out fairly well. In the front of the kiln they got hot enough to become a little more glossy than they were in our test kiln:
Still pretty nice though.
In other parts of the kiln they were much closer to what we were expecting in from the our testing in the small gas kiln.
The green ash glaze was pretty good, though it did run more than we expected, and pooled blue in the center of a few bowls:
This one is a nice example. However in some cases the blue completely masked a decoration I had inscribed in the dish. All in all though I think this glaze is a keeper, we'll just have to use it a little thinner than we did this time, and be aware of it's tendency to run.
The black glaze on the other hand
not so black. It also turned green where it got hot. We don't hate it, but we'll probably keep working on this glaze to see if we can't come up with something better.
That pretty well covers it for news from our last firing. A couple more pots from this last firing:
Christy's been working on different handles for her boxes:
Another nice example of our white glaze:
A large unglazed jar from the front of the kiln. You can see a color change right where the two pieces of the pot were put together. Not sure why...same clay...
not bad though.
Thanks to everyone for encouraging me to try out curved teapot spouts, they are really starting to grow on me.
