For a full description see: http://www.improvedconcretecookingstoves.com. The stove has got four parts: chimney(s), a chimney block, and a semi-circular combustion chamber. All parts are made of locally produced burnt bricks. They are finely granulated and mixed with cement – ratio 3:1. All outer moulds are slit from top to bottom so that they can easily be opened when the moulds are to be removed. They are held together by 4 mm cords tied around them in two or three places depending on the lengths of the moulds. Inside the moulds two kinds of wooden rings are used. The combustion chamber is divided into two cylindrical parts by plastic or acrylic rails. A wooden brick is fastened to one of the dividers. A round wooden stick is fastened to the top of the other. The wooden parts of the dividers serve three purposes: to secure the same distance everywhere between the inner and outer moulds when casting the combustion chamber, to provide an opening at the bottom of the chamber for fire wood and air, to allow smoke to pass from the chamber into the chimney block at the top of the chamber. The same cement mix is used for all parts of the stove. It consists of locally made burnt bricks, which are granulated and mixed with cement, ratio 3:1. The mix should be so stiff that it is possible to make a ball with it. This results in a flameproof light weight concrete stove, which is semi-insulated and ready for use after nine days. The chimney block can be connected directly to the combustion chamber or it can be connected to the combustion chamber by a horizontal piece of chimney. A hole is made in the kitchen wall for the horizontal chimney, which connects the combustion chamber placed inside the kitchen to the chimney block outside the kitchen wall
