Sagger fired bottle 05. Sagger pieces are fired twice. The first is a (bisque). The second firing is done in the Sagger, that is, a container filled with minerals, wood shavings etc. Sometimes the piece is wrapped in seaweed or other materials to get color. Salt is added to the Sagger along with other materials in the attempt to get an interesting surface. The Sagger is placed in a fuel burning kiln in my case a gas kiln and fired to about 1800 degrees. Every piece is different Most pots are fired several times to satisfy the artist.one of a kind. http://www.ronmellostudioart.com/index.html
