Here's a look at the new pots
There are always surprises when I open the kiln, particularly when there are new glazes or new forms or new combinations of glazes in there. That happens a lot. I don't do anything consistently, which is either a virtue or a vice, depending ...
Fortunately, I like surprises. That's why I like wood-firing, though I don't do it often enough. And that's why I use Shino glazes and combinations of Shino glazes in most firings in my own gas-fueled kiln. This time, the three overlapping Shino glazes on the many square hand-dug brown stoneware cups and vases and the dug-out teabowls worked out pretty well. I used Bright Shino as a base, pouring a Malcolm Davis carbon-trap and a Davis orange Shino over the base. On some of them I poured the Phil Rogers ash celadon I use as a liner. The ash sometimes does nice things over Shino.
There was a fair amount of crackle slip in this firing, which works well under the ash celadon and under the blue ash recipe adapted from blogging potter Brandon Phillips. (Thanks, Brandon.) This blue might still be a bit strong for my tastes, but cobalt is a strong colorant and I mixed a smallish batch, so I might have had a bit more cobalt than the .10 percent called for in Brandon's recipe.
The two faceted vases and the creamer between them are glazed with a basic ash glaze that is four parts Antarctic sea mud and five parts wood ash. That recipe produces a glossy amberish glaze with nice running and pooling qualities on the B-Mix white clay body and with crystally brown/amber qualities on brown stoneware.
All in all, not a bad firing.
