Mosiac Tile (Upside Down) Under Pizza Oven Insulation - For Drainage - July 2024
With the foundation and stand complete for our diy'd wood-fired pizza oven, I recently started turning to building the *actual* oven by cutting bricks last week. The process of starting the actual oven begins with prepping the top of the hearth to accept the calcium silicate insulation boards.
