Default Re: How cheaply can an oven be built?

Robert, for about $20 US, or a trip to the library, you should look into Kiko Denzer's "Build your own Earth Oven" book. He went through a lot of important principles and compared various oven types. The clay dome with brick first layer was pretty easy, and these types of structures can last for hundreds of years if cared for.
The one major difference I can see in the clay versus brick/concrete debate is that clay will need to breathe, so you'll have to do a roof or keep under a tarp rather than seal the dome.

Firebrick has a higher aluminum content than regular clay bricks. This makes it more efficient at soaking up and dishing out heat than clay bricks. Yes clay bricks can be used to make a functional oven. However, the firebrick gives much more efficient use of fuel and retains heat better, even with insulation.

Exclamation Re: How cheaply can an oven be built?

The Olde days were labor intensive.....
Thats the thing that put me off clay was the amount of effort required. Sourcing suitable clay (Im on sand) getting it back, crushing it to powder mixing in water and straw, making cobs to construct the dome. Lot of effort from the little reading I have done most of these construction inlist the help of friends and neibours. With brick ( firebrick or common) that parts already done and the clays fired rock hard as well so you can get on with the construction single handed. I enjoyed me sat morning construction time... did things bit by bit with no time pressures...the oven could just sit in the rain till next week.
The main thing is to build an oven whichever type and enjoy the journey

regards again...dave

Well I have broken ground!
I had to fix up the drainage in the area where the oven is to go. I am aiming to get boxing and steel done this weekend coming and pour base the week after.
I have a length of SS tube 6 inch in dia, 100 besa bricks ( cheap off eBay) and kinda got a plan together. Cast in place 900mm ID.
Will let you all know as I go.
Rob

I really dont think you need too much rebar in the vertical hollow blocks? Or even need to fill them? The weight of the base will hold everything down! I have seen somewhere that you can use ordinary CLAY bricks for the dome. Yeah, I live in an earthquake zone, but the oven would be the least of my worries if we had a rattle! I have not checked out if the oven will effect your house insurance in any way, anyone know?

Well the oven is still underway !
Grounds dug for the slab, but several days of storms in a row has made the site very wet.
And if the weather was against me, it seems my body has plans to stop me also. I have a ganglion on my wrist thats been fine for years but now has decided to give me hell. A trip to the doc and he has sent me to a hand surgeon as the damm thing is in a spot where no one want to operate. This is makeing my Christmas day cook off looking a little shakie,,,,,

I do have a question for the crew.
My 2x20 pound gas bottles for the house are apx 10 m from where the oven will be.
Is this a problem?
I am thinking no as the gas BBQ I own has a flame 2 foot away from the gas bottle and I can always check for leaks at the gas bottles before lighting wfo. LPG is also heavyer then air so any leaking gas should remain a ground level and is out in the open, never had a gas leak... Am I just worring for nothing or find another spot for the wfo???
Any thoughts
Rob

"So , are we better using a simple clay brick for the dome, or is a fire brick still the best answer ???"

The true fire brick will last much longer, probably forever. Normal clay building bricks will tend to deteriorate over time and you may find yourself rebuilding your dome after 4 or 5 years of use.

I am still planning the oven, thinking cast in place still. Enough people have done it to make it a proven method. Just need to get the other issues sorted
