Hi, I am looking for advice from someone who has some knowledge/experience with brick ovens.
I was just visiting a friend who had a backyard addition and decided to added a brick oven to the project. When I saw it, I was confused by two design elements: Chimney in the Center, Mortar between the bricks on oven floor. Are either of these serious issues / hazards?
I had never seen a brick oven with the Chimney in the Center of it. Also, the floor is fire brick, but it has standard mortar between the bricks; I am almost confident that it is not vermiculite or Refractory Fire Clay. I am concerned that instead of a wood burning oven, the mason built a really big rocket stove.
Thanks for any thoughts. (Here is a poor video of the inside)
