What's interesting with shiralite is you know it's dry by the color it turns. Acquired a burner like Liteceeper used. Will double as a paella burner moving forward. Of course I can use oven too.

Yes what you doing is sensible, you will be drying the oven out at the shiralite stage which is great as you will not arrive at the end with a huge mass of wet oven.

Colin,

Lots of ways to skin the cat, sometimes ya just got to do what works for you.

Re: new build in werribee

I agree with Dave. I took the advice during the build to cure while working finishing oven, all the moisture was gone by the time I insulated.

I had cooked quite a few pizza's whilst I was waiting to finish.

In fact, the insulation was on for some time before final vermiculite and render layers applied (covered with a tarp).

Over 12 months later, I only have two small cracks in outer render, and these are near the vent where I know the blanket was not applied as well as the rest of the dome.

Cheers

Unless you get the insulation done? It will able to be used without it. Never really made up my mind completely on which way to go on when to cure. I lean towards curing the dome shell before insulating. My gut feeling is there is to much water trapped by to many layers and a lot of a lot of ovens and they crack due to steam.
My own experience was the wood form was burnt out and I used the oven before I used dry insulated and rendered. Min moisture and only a couple of hairline cracks in the entrance due to having steel supports.
Using pearlcrete as a layer above the dry insulation I don't think myself is really required and only adds extra moisture and complexity to the build. You can render over dry insulation and get a good shape. If fact pearlcrete is a sh@t to work with and the water pours out of the stuff into your dry insulation which can't be good. Render is much easier to work into shape than pearlcrete.

thanks Dave and Craig

I understand both your points of view and have agonized over this one, especially considering that everyone has done the reverse of what I am doing.

However, after much consideration and views from 3 commercial oven builders I have decided to use Shiralite around the Dome to insulate and lock the bricks in place. It is used in Commercial oven builds in this order and suggested to me by someone that has been in the oven building business for 30 years. I then researched it too death.

Once this is layed over the Dome I will begin a slow and steady oven cure.

Once the Shiralite has dried [very easy to tell] I will then begin to apply the Blanket. Now I know various builders out there say always use the blanket first as it is a better insulator but insulation is insulation. My view after research is that blanket is flexible so if using 75 - 100mm of blanket then vermicrete, then Render. Then you have a soft layer over the oven. Its just a view I have that differs from the norm.

I do intend putting in a vent at the top of the Dome like yours Dave which by the way I must go and get before the weekend.

I built a Utahbeehiver special today.
