Brick Antique Pizza Oven

I built a pizza oven in my garden about 4.5 years ago. I used it once or twice to bake pizza, then left it as is until I recently dismantled it.

There are 5 long, flat bricks.
There are about 4.5 regular-sized bricks that are broken.

There is also an iron plate.

There are around 90 regular bricks.

Since there are so many,

This is for pickup only in Abiko City, Chiba Prefecture.

I didn't buy them myself, so I'm not sure, but they are likely firebricks.
