New Shino teabowls from the Aug. 23 firing
I seem to be fixated on teabowls lately. That will not come as a surprise to anyone who has looked at this blog in the past few weeks. This firing was no different, with a dozen or more teabowls on the bottom shelf, most of them glazed in layered Shino glazes and sifted wood ash. There were bowls and vases in the firing, too, but right now the teabowls are my focus.
Something seems to happen to both of the Shino glazes I'm using when they are combined on the Miller brown stoneware clay body that I use. The Malcolm Davis carbon-trap Shino takes on a sheen it usually doesn't have on its own, and the so-called Bright Shino usually goes white against the sheen. My runny ash celadon on some of them adds another layer, as does the wood ash shaken randomly across the surface.
There is a random landscape that is created with these combinations that is never intentional. I don't know which side will trap carbon. nor where the second Shino will go white. Glazing for this firing, the Bright Shino bucket was down to a few ounces and I was too lazy to mix up a new batch, so I resorted to dripping from a measuring cup. Spots and runs resulted, rather than great sheets of the whiter overglaze. Some got ash glaze, most did not. Almost all got ash.
There are, also, cups here in Shaner Red with sifted ash that turns the glaze yellow and runs down the side. And a couple of simple temmoku cups that are pretty quiet.
The detail of the glaze alone is from a low pasta bowl that's been marked on the inside by a chattering iron.
