As long as you think that will solve the problem, I'm all for it!

Thanks for the input!

I can use all the help I can get.

Now if I could just find some vermiculite or perlite around here...............somewhere.....................! !!!

I second the two inches idea - then you should be far enough from the edge that you are only dealing with compression, no shearing forces. Don't add an extra step of wrapping it with mortar - needless work.

Yep. I think that's the way I am headed.

I appreciate the input on this issue.
I'll let everyone know how this works out.

Luckily, I finally found a garden store in town that has ONE bag of course perlite.

No vermiculite to be had. I'm not sure if one is enough... for this part.. I know I will need more later, but the owner said he can get more when I need it.

Thats good. Perlite is a lot easier to handle anyway. I hate vermiculite.

Sweet.

That's nice to know!

I'm feeling better about this weekend!

Dave - when I was building my oven and looked up insulating values perlite is marginally better then vermiculite. One more nice to know item.

[asudavew]

Well I built my forms for the oven base today.(Sunday)

And then mixed my insulating layer. I began adding the mix to the forms, and blew through one bag of perlite like it was nothing...........

Unfortunately, it was the only bag in town. So I ordered two more, but they won't be here until Friday....


I will post some pics of my form and some of the tile work I started today.

Bummer!
...Glad to hear I'm not the only one these things happen to though:-)
I seem to spend half my time waiting for things to dry/cure/arrive.

[asudavew]

Well here are some pictures of my insulating hearth form and partial perlcrete pour.

I also did a little tile work.

So I will post those pics too.


These first are building the forms, and leveling the top of the forms for a level cooking surface.

I redrew my floor circle. I didn't like the string method. It wasn't very accurate.

So here is what I used to redraw the floor.
