Oxides Study #2


Coil built. Refractory clay with mixed cobalt carbonate. Transparent glaze.

Fired in gas kiln at 950 degrees (centigrade), then put in reduction environment (raku technique).

I made this piece after a sketch, because of its proportions. It is not intended to be used as a functional piece. However, it would be interesting if it had a fern like plant growing inside. I keep it empty though, as I like to admire its proportions.

The Oxides Studies Series is composed of works in which I studied the effect of oxides mixed in the clay itself, or of a slip with a high percentage of oxide. In all of this pieces, the colour is achieved by the presence of those oxides in the clay or slip, under the glaze, which is transparent. The technique used to fire the pieces was raku. Raku has it’s origins in Japan, and was recently adapted by westerners. In this technique, the piece is heated and taken out of the kiln while hot, and usually put in a container with combustible material.
