Default Fire brick mortar

Hi, I am looking for some help with the thicness to apply the mortar between firebricks, the guidelines indicate 1/8" maximum, but It will need to be thicker towards the outside of the dome where the bricks splay out.
Is it okay to use a thicker joint here.
I would welcome any help

Yes you can use a wider joint at the outside, you will need to unless you go crazy with cutting and fitting. What mortar are you using?

From the Victas site:
Victas heat proof mortar is suitable for all kinds of INTERIOR use, but must not to be used outdoors.

This looks like a premixed air-set product. Some people have used this successfully, but it will remain water soluble. Better to get a dry refractory product if possible...

I will look for a dry refractory product as suggested, not easy to find in the Uk so far, Vitcas assured me it would be okay as long as it was weatherproofed.
This is a great site, really helpfull.

I'm with Drake on this.

It's very difficult keeping an outdoor oven dry -- no matter how hard you try to weatherproof it. The issue is that the binder that holds the mortar together comes apart when it gets wet. Not good.

Doesn't burning the wood and baking produce water vapor. Is it enough to damage the air dry mortar or are things too hot in there?

It's the rain, fog and mist. The mortar can't ever be exposed to water.
