Thanks Thomas.
First I’ll build a J-tube with stratification chamber in November.
Then maybe a batch box in our house, once we finally signed the contract.

A little update from the pizza rocket.
I am very pleased with the performance. Heats up in roughly 15 min, fairly easy to start.
There is some smoke sometimes and some soot collects on pots ect.
But I really enjoy baking and cooking in and with it. Bread in clay pots, oven vegetables on a sheet and some beans or lentils all at the same time with the oven rack system.

Oven packed


In the picture you can see the slits where the hottest air comes out from under the "pizza tile". When using a tray to bake potatoes or other vegetables I like to prop it up with 2 of the T-bars so it's not in direct contact with the hot tile.
And the bread goes up on the rack.

Oven rack system


The rack system are just bricks with cuts and t-bars that span. Like this I can put something on the bottom and something on top. And switch it up according to need.


When making pizza I noticed the pizza didn't get enough heat from the top. Understanding physics was key to come up with a solution.
The hot air does collect in the vaulted ceiling and needs to exit at the bottom of the oven. So the ceiling does get nice and hot. So far so good.

Oven vaulted ceiling


But the ceiling is far away from the top of the pizza and heat radiation is governed by the inverse square law.
So I took a thick metal plate, cut it in half to fit through the oven door and put it on the upper rack when making pizza.

Metal sheet for higher pizza radiation

This way the top of the pizza gets crispy cheese at the same rate as the crust gets perfectly browned.
