The Cob Oven: DIY Outdoor Kitchen/Pizza Oven
Cob was widely used in Europe in the 16th through the 19th centuries and many of the structures built using this material continue to stand and are still in use today.Cob is a simple mixture of clay, sand, straw and water. It is mixed to a consistency that is wet enough to shape, but dry enough to layer up without the use of forms or skeletal structures.
Generally it is mixed together by foot but can also be mixed by machine. The material is ideal for molding into any shape, lending itself to curves and sculpturing. Cob is incredibly durable and with a solid roof possesses a resilient ability to withstand fluctuations of weather
