Re: Started my pizza oven

Hey Daniel,

I think 3 1/2" (3" of FB Blanket and 1/2" for lathe and stucco) works for the enclosure, but don't forget to calculate in the thickness of the oven dome.

If you can find the space for a 35" (internal) oven, rather than the 31", I think you will appreciate the extra space when it comes time to start cooking.

Re: Started my pizza oven

i drew a 31" diameter circle and that looked too small. If i go with a 35" inner diameter and leave 3 1/4" on each side for the enclosure and insulation what is the down side to this?

Re: Started my pizza oven

my plan was 52 - 7" for 2x4 framing

You will have to cover that with something, most likely 1/2 inch Durock - that will add an inch.

You may consider using metal studs - if you rotated them 90 deg. and with proper bracing, it will save you a couple of inches. Another thought is to use 1/3 brick - don't know if anyone has done it but I see no reason why it couldn't work. And one more thought - if all you are after is the elusive pizza, you could skip the insulation altogether. I don't recommend it because I feel that you should get more out of a firing than a couple of pizza's. The difference in labor between a small oven and a 42 inch one is pretty much squat, I would try and squeeze every millimeter that I could out of it.

Just my thoughts - Good luck.

Re: Started my pizza oven

my plan was 52 - 7" for 2x4 framing - 5" insulation 2.5" on each side - 9" for firebrick = 31"

what do you think. Im laying the floor now.

Re: Started my pizza oven

To max out your hearth, you could try:

1" stucco enclosure (2x1/2")
6" FB blanket (2x3")
8" dome (2x4")

That gives you a 52"-15" = 31" oven. Not bad.

Re: Started my pizza oven

You put rebar in the vermiculite? Probably very little harm, but I think you are the first to do it.

In regard to size - I'm seeing around 27 inches ID. 52 - 8 inches for enclosure - 8 inches of insulation - 9 inches for the size of brick = 27 inches. Of course any of the above numbers can be tweaked.

I was limited in the space i had so my oven floor is 2.5" of concrete and rebar and 3.5" of vermiculite and portland with some rebar. My hearth measures 55" deep by 52" wide. What size oven is recommended with this setup? I need to know the inner diameter of the oven.
