Casa 100 hearth/arch questions

[stchang]

I've restarted my oven that I started last summer, and I'm at the stage where I need to decide how to finish it. I had some questions...

Can I lay a slab of granite adjacent to the Casa 100 opening? If I can should I use refrax to mortar between the Casa 100 floor and the granite? My idea was to put a ledge of granite across the front of the oven.

So if I do that, can I build my brick arch on top of the granite?

Thanks for any advice,
Steve

Yes, granite is a good material for that surface. Just don't build a fire on it.

Sure, if it's supported from below.
