The video bellow shows oven firing for bread.
Depending on the regularity of use, the weather and the size of the loaves the firing could last from 30 minutes to 1 ½ hours. If the oven is used often – every few days – the firing time is shorter. If the bread loaves are large the firing is longer.
The wood must be dry and it is advisable to use thin branches, so that an even heating of the walls and the floor takes place.
