3) Assemble your terracotta oven.
4) Grout the joints only on the outside of the oven structure using scagliola plaster or plastic cement. The upper layer of insulation must measure at least 10 cm at each side of the oven and 20/ 25 cm in the upper part.
5) Apply the ceramic fiber all over the oven structure and secure it with a large-mesh, flexible metallic wire.
OVEN BASE FINISH: As shown in the picture above, pour vermiculite until all spaces are filled (10 cm at each side of the oven and 20 cm in the upper part).
IGLOO FINISH: blend vermiculite with cement and water and spread the mixture all over the oven structure.
