Once we arrived at their house the oven was already lit for a three hours and the temperature inside the oven was about 700 °F. They had built the oven themselves!
The oven structure had three parts: the exterior decorative brick, the interior made with fire brick, and in-between those two they placed a steel drum. This way the heat generated inside the oven wouldn't escape easily. They also cut a window (to insert the food etc.) and they also made a door to prevent the heat from escaping.
The logs had become charcoal and the temperature was high.
