 <\/p>\n

I am going to try and make a pizza oven !<\/span><\/p>\n

Has anyone made one or know someone who has ?<\/span><\/p>\n

1st. Not sure what to use and where. Vermiculite, perlite, brick or firebrick?<\/span><\/p>\n

2nd. Is it better to use a form or a mould?<\/span><\/p>\n

3rd. Is it possible with \u20ac150 to spend ?<\/span><\/p>\n

Any advice most welcome !<\/span><\/p>\n

Unless you know better i sure this part is done.<\/span><\/p>\n

The wooden support for the flue pipe is incorrect. It should be a deeper piece of board or two supports, so the flue pipe does not twist.<\/span><\/td>\n

MK2 Base and Form
\n<\/span><\/p>\n

 <\/p>\n\n\n\n
\"\"<\/td>\n<\/td>\nMK2 built in the frame on the stand. After the MK1 failure due to inadiquate concrete mix, we reverted a more contemporary base construction.<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n\n\n\n
\n

I also added another course of fire brick, so that the dome will will now sit on the fire brick, instead of the concrete base.<\/span><\/p>\n

I also also added pencil rounds to the form, hoping it would cast a brick effect arch. This did not work out too well do to the wrapping in cling film, as you can see in the next photograph.<\/span><\/p>\n<\/td>\n

<\/td>\n\"\"<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

 <\/p>\n

Cling film was added to the form to aid the reslease, of the concrete later.<\/span><\/p>\n

120kg of sand was built around a cardboard form, using he cardboard form as an guage to create an accurate dome.<\/span><\/p>\n\n\n\n

 <\/p>\n\n\n\n
\n

After allowing 3 or 4 days to dry, we slide the form, and dig out the sand and carboard, to reveivel 60cm internal surface with 30cm dome.<\/span><\/p>\n

Once its hot should have about 60 x 35cm cooking surface.<\/span><\/p>\n<\/td>\n

Sometimes you need to rethink things. I had to put the door in water to stop it caching fire. Then the oven got up to over 500oC, working with what I have on site I came up with the MK 2.1 cast door.<\/span><\/p>\n\n\n\n

Oven Fuel<\/span>

\"\"<\/td>\n<\/td>\n\"\"<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Oven fuel arrives, this should keep the oven going 3 times for 2 years. We need to make sure the wood is properly seasoned, or we will never reach the temperatures needed.<\/span><\/p>\n

One thing i found out along the pizza oven trip was not all fire wood is the same... if you want to get a good pizza you need to spend as much time on the wood as you do making the pizza.<\/span><\/p>\n

Firing The Oven Up<\/span><\/p>\n

 <\/p>\n

I lit the 3rd little fire got the oven all the way up to 45oC i have to keep doing this about another 10 to 20 times slowly getting the oven hotter every time once it get to 240oC i am told its pizza cooking time....<\/span><\/p>\n\n\n\n
\"\"<\/td>\n<\/td>\n\"\"<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Made rain cover thing, well its will do for now, I can work with the cover up and pull it down when I not working.<\/span><\/td>\n<\/td>\n\"\"<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

 <\/p>\n\n\n\n

\"\"<\/p>\n<\/td>\n

<\/td>\nFinished the rendering around the door and made a pizza loading thing, from a bit of mettle and 2\/3 of the brush handle will use the other 3rd to make I fire hook...<\/span><\/p>\n

I found a few broken tiles which tomorrow I will cut and fit around the outside then give it a lick of paint....<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

 <\/p>\n\n\n\n
Tiles fitted, I only had a few broken once, so i had to patch up around the back of the dome, but you dont look at its ass when your poking the fire.... better rain cover and paint i think thats about it.....<\/span><\/td>\n<\/td>\n\"\"<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n\n\n\n
\"\"<\/td>\n<\/td>\noh yes cook a pizza .... does anyone know how to make pizza dough may be i should have look at that 1st.<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

 <\/p>\n\n\n\n
Fired her up this morning with longer flue pipe fitted after a slow start she got upto 134oC captain, she held at 70oC for hours after.... it did not blow up, crack or anything, looks like the Mk2 is holding... i will light her again today, once it cools right down.<\/span><\/td>\n<\/td>\n\"\"<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

 <\/p>\n

Almost cooking time not everything in life works the way we plan it,, like paint I got from China R Us got the better one paid \u20ac9 for 500mls, only thing it wants to stick to is its self... but hey its only paint and if it does not stick, it not a big job to repaint..<\/span><\/p>\n\n\n\n

Fire lit and dome got to +260oC the top hit over 400oC its so hard to get a good reading, so I put an little bottle, I found in the door.<\/span><\/p>\n

I just started taking temp reading of the bottle and its at 120oC... <\/span><\/p>\n<\/td>\n

I did not think it would get this high so just \u2026. but I know why... its was the wood I got I was told its seasoned if it is it need longer... I dried the wood I used this morning by the fire last night... that's what did it simply drying the wood before I put in it the oven... next stop Pizza<\/span><\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
