9. (B) Adobe Layer

1. In a wheel barrow mix adobe by combining 5L clay with the previous recipe for refractory mortar (70% clay soil, 20% sand, 10% cement).

2. Smooth this in an even layer over the entire pizza oven. This gives a nice uniform surface to attach the nest layer to and begins to provide some insulation. Work with a trowel for even and smooth coverage. 

3. Dry this layer for at least 24 hours. Use tarpaulin to protect from rain. Again lighting a small fire in the oven after a good period of drying time will help rid excess moisture. 


NB: This layer may crack while drying due to the high amounts of clay. It will not make a difference to the final structure.
