Experimental glazing - shino

Wheel thrown small bowl, bmix clay, shino

Some glazing experiments don't turn out like you expect them to especially when using Shino glazes!  I had found in the past that brushing thick shino glazes while they dry on a pot's surface after dipping can produce an interest textured glaze.  You can see in the black areas the brushed texture on the outer surface of the bowl.  Unfortunately, the shino kind of went crazy in the kiln and pooled instead of making a smooth continuous surface - hence the crazy lava like look (which I dubbed kona bowl).  I don't know if someone would want to eat out of a bowl that looks like this but I think it is an interesting piece to look at nonetheless.  I tried some masking and different glazing with the vase below, including sponging on slate in masked areas on the vase exterior.   I like how the inside of the vase looks with the drips of kaki and slate blue contrasting the color of the fired recycled clay.  I'm thinking I'll try that again in the future.

Celadon bowl

Recycled clay, CuCO3 stain and celadon glaze, reduction
fired.  Wheel thrown and carved
Probably the best bowl I've thrown so far since the shape is very functional - good sized foot, thin walls with a delineated rim, profile is easy to pick up and set down, and the size is good for eating from.  I carved out the texture on the outer surface of the bowl and foot - I think I much prefer textured to smooth surfaces for aesthetics.  The dark and burgundy areas are from copper stain that I brushed before glazing over with celadon.
