Newby Questions on Construction
 
I hear soap stone is the best heat convector… is there a product that would tolerate heat and hold it upside-down in the dome? Any info on non toxic cement products? Is it necessary to have a door/gate, if so sources? THANKS!

be more specific what you mean? do you want to hang bricks?
Regarding the door question....you could avoid a door if you would use the oven only for pizza, but for baking you do need it.

if you want to hang means you already have a dome? right? made of what?
what's the scope of hanging bricks on an existing dome?
I would not trust any mortar for this scope.
The 2 main mortars used by everybody on the forum are Remix and HeatStop50.

Here's the FB primer on mortar:

http://www.fornobravo.com/forum/f6/h...rimer-914.html

By all means I suggest using a pre-mixed dry mortar like refmix, or heat-stop. It's easy to mix and spread, and hardens to a hard, waterproof bond. Clearly expense is no object if you are building your dome from blocks of soapstone.

I don't understand the adobe question at all. Cadmium? Isn't it just mud?

I speak newbie (since I am one also!:D ) I think he is asking how to "hang" the soapstone to the interior after the adobe oven is formed. Yes?

If so, you need to rethink your process and lay your soapstone in a dome form first with a refractory type mortar. Once that's done, you would coat the dome with the adobe mixture.

Or, I'm way off base?

Hmmm.... or have you got an existing adobe oven which you want to clad with soap stone internally?

Metals tests are not that expensive....if you're really worried about the heavy metals in the clay, do a test. A lot cheaper and easier than trying to line a clay adobe oven with soapstone! It would probably be about $25 to test the clay for lead or cadmium....call an analytical laboratory for pricing.

I really doubt that it would be a problem!

Where does one buy soapstone blocks or flooring anyway? Send me a PM if you know of a source for the oven floor! otherwise it's firebrick for me.
