How does one build an outdoor brick pizza oven, without using pre-made oven materials? Can I put one together using old fashioned brick and Portland cement? I've seen a couple internet posts that suggested one can use gravel and pavers as base, and using carboard to set a dome mold and using regular bricks and portland cement to build the dome. A meter or 1.5m diameter dome, with an opening enough to get a pizza in.
What do knowledgeable folks here say? Can I build a pizza oven for cheap?
