Adding a splash of color and getting crazy with glaze.
Believe it or not, the reddish-brown and yellow colors are iron oxide blends and turn very muted or rust-like looking after firing. I expected this to happen to a degree (especially with red iron) but what difference! Korean celadon, and a white liner glaze were also added before firing. The clay has some iron in it as well, and turns much warmer in a reduction atmosphere. Fired to cone 10.
