I am investigating ways to construct a wood fired pizza oven.
I am currently experimenting with ways to reduce the cost and complexity of building it.
The attached photo is mark 2 of my current oven. Constructed from house bricks (salvaged from the BBQ that was there) with a paving slab on top, sealed with mud. All high tech

Internal square of 600mm.
So far so good. Obviously it needs sealing properly (when it smokes to start with - the smoke comes out everywhere - very funny) and insulating. But it seems to get pretty hot already.
Comments? Advice?
Thanks
James
