Oxides Study #3


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

Fired in gas kiln at 950 degrees (centigrade).

2019, Alexandre Carvalho


In this piece I wanted to see what metallic effects I would obtain by the technique of raku, using clay with high proportions of oxides. The bottom and the middle part of the piece show some of those effects, and that´s the interest of this piece. It also is not a straight piece, and from the first to the second piece (from bottom to top), it makes a slight curve which I appreciate.

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.
