Chimney Sweep preserves pot produced by W. Goebel Porzellanfabrik of Bavaria, Germany, in 1972. A chimney sweep is a person who clears soot and creosote from chimneys. The chimney uses the pressure difference caused by a hot column of gas to create a draught and draw air over the hot coals or wood enabling continued combustion. Chimneys may be straight or contain many changes of direction. During normal operation, a layer of creosote builds up on the inside of the chimney, restricting the flow. The creosote can also catch fire, setting the chimney, and potentially the entire building, alight. The chimney must be swept regularly to remove the soot.
