This piece was thrown on the potters wheel and then gently altered. I ruffled the edges and texturized the piece. The piece is made of a soft white stoneware clay. I signed the piece prior to firing in an electric kiln to 2167 degrees! The perfect 9th Anniversary gift, Wedding gift or Birthday gift! The piece measures 8 inches across and 4 1/2 inches tall and is hand glazed ina lovely shade of emerald.
