Oven Building for all ages
  • Oven Building for all ages

    We begin by talking about clay, where to find it naturally, how to mix it with fibres and sand to prevent it from cracking when dry, mixing the cob with our bare feet where possible on a tarp.  We will build on top of a mold, which is our inside of the oven.  We will mix two mixes, one for insulation, and one for thermal mass, principles explained throughout, optional chimney integrated. 
    Learning Outcomes:

    Learn the fundamentals of using cob (clay, sand and straw-mixed) to create your own garden oven, capable of reaching a temperature of 500 degrees Celsius.

    Cob is a thermal mass material meaning it can store heat for up to 12 hours, gradually decresing. These ovens are probably one of the most economical ways to cook. Perfect for pizzas, sourdoughs and other breads, and slow roast stews left in oven overnight when you are finished your pizza parties

    Learn how to source your own clay, where to look for clay, the differences between clay and soils.

    Perfect combination of clay, sand and fibers for expert builds

    How to make your own clay bricks for arch of door, and use an all natural clay/sand mortar for joining principles of fire flow and thermal mass.
