Teaching a cob oven workshop in Williams, Oregon.
Local clays and grasses to work with
Urbanite and strange concrete blocks to bury into the foundation.
Making adobe bricks to build up the foundation to a good baking height. I made a trapezoidal form so that we could easily create a 48" diameter circle.
Laying the adobes, with glass bottles inbetween
The insulation layer which will be underneath the baking surface. This layer of glass bottles and sawdust will help keep the heat in the oven from escaping through the mass of the base.
The baking surface made of kiln bricks and a wet sand dome which will serve as the mold for the oven.
After building up the first mass layer and arch for the doorway, we can remove the sand form.
