Re: we have built the base.....

we are worried that we have gone too high with the base?

Actually though, sometimes higher is better. It is more comfortable to work the oven if you don't have to bend down to look in it at all. Look at professional pizza ovens, they are often up a shoulder level...

Re: we have built the base.....

I used a mix of 1 part cement, 6 parts perlie and 6 parts vermiculite. I think the mix makes for better worability.

Be sure to mix it dry first then slowly add water then mix gently. It does not take much water. Avoid overmixing when wet or you will break down the perlite and vermiculite particles - reducing the insulation effect. Don't use a machine - do it by hand in a wheelbarrow.
