did i use the wrong mix
 
First, thanks for this forum -

I downloaded the Pompeii instructions several months ago and started construction on a 1200 sqft fieldstone patio with oven last week.

I poured the base last week for the Stone House oven and now realize that I may have used the wrong mix. I didn't use vermiculite - just regular concrete - is this a total screw up?? I plan on using the fireplace a lot - will it be okay to just use the firebricks on top of the reg. concrete??

Hi Mini,

Welcome aboard! I moved this to Getting Started. You should get more help here.

The hearth under the wood oven has two layers. A concrete slab, that holds everything up, and on top of that, a layer of either vermiculite or FB Board insulation. The oven floor rests on top of that.

If you follow the plans, I think you should be OK.

Don't put the firebrick directly on regular concrete. You need some form of insulation, or you will lose all of your heat, resulting in a cold floor.
