Perlite Traditional Pizza Oven

After the "small experimental pizza oven" i can observe that:

very fast increase of temperature until 600°C degree but same fast loose of temperature when not put burning wood inside so is easy make one or two 25cm ø not more than the temperature fall rapidly.

It is smart portable and light.

For make more 30 cm ø pizza and bread and cook something in dutch oven or "Peca" I will have a little more big wood oven with temperature constant for long time

Ergo I need a small traditional fixed refractory oven. I decide to use perlite expanse small drop of stone treated at high temperature that have very high insulation proprieties.

Perlite

Refractory cement concrete

Normal concrete 325

a lot of lay make with perlite refractory cement metallic net and perlite with normal concrete

Need a strong card board template to make the dome

Gentle put the perlite and refractory cement to build the inner layer

To give the strength need a new layer made with perlite metallic net and normal concrete 325

turn up side down to remove template and finish the inner layer

To make a good base I used empty bottle to have insulate layer and no climb water from down then a base of refractory brick

I put in place the oven and use refractory cement to fix it

After a week (better more) the first fire slow start and slow go up with temperature take the fire all day long

note the cat supervision

then must add a lot of layer with perlite and concrete to increase insulation

need a lot of day with every time increasing fire and temperature to dry the oven need also a perlite door to cooking with dutch oven or peka (long low temperature cook)

I use a special with concrete that not adsorb water

Now I need a right pizza shovel for 30 cm ø pizza
