Oxides Study #1


Refractary clay with mixed copper carbonate. Transparent glaze.

Fired in gas kiln at 950ºC

2019, Alexandre Carvalho


In this piece one of the coils on the top of the piece broke due to the extreme conditions of the raku firing technique, and adhered to the glaze and flowed down the wall of the piece, and by the end of the firing it was lodged near the foot of the piece. It was a surprise to open the kiln and finding out of that fortunate accident.

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.
