I find it a little risky adding cobalt brushwork to a bowl.
An off day with the brush can leave the previous weeks work of throwing and bisque firing wrecked*. So after a 48 hour glaze firing, opening that kiln door to see the results can be quite inspiring or a real downer.
Luckily I found this bowl greeting me when I opened the kiln this morning.
*cobalt intensifies after firing. So the results can't really be seen when raw (unfired).
