things have got a bit hard to context into classes, so this one is the post of stuff out of the kiln fired yesterday.
a nice reduction test, using copper and leach glaze forumla. looking into the bowl we can see the nice coppery colour, that's been speckled into the red reduction. *sigh* it was meant to have been so heavily reduced only around 2/3rds of the bowl. yes it's also got no centre, these things happen when learning to turn feet into bowls - sometimes you go straight through the bottom. i fixed this up so it atleast looks like it's meant to be there ;)
the side shows the nice apple green to red effect. if i'd rotated the bowl there is a large part you can't see any green and the red is very rich. grrrrrrrrr i intend to try again, but have the bowl in the centerish of the kiln (not right next to the flame as i disscovered it had been).
these two guys are testing my underglaze pencils i made up. same clay body, one the left it's earthernware fired (and clear earthernware glazed), and the right it's stoneware reduced (clear stoneware glaze). the blue and red pencils work fine, the 'reddy' one needs more oxide in it i think.
