Wow....so much information so far....thanks guys.
Frosty, you kind of lost me at the rigidizer. I'll add the link below, but this is what I was planning on using as a refractory. So basically what you're saying is I in need to coat my final layer of Kaowool (I assume 4 layers as it's half inch thick) with this kiln wash? Or would I coat each layer? That said after the kiln wash I'd use the mentioned refractory? Also, THAT said, basically look for kiln shelf to use instead of fire brick?
Onto on the pipe fittings, yes I haven't looked into the plumbing stores and they generally don't sell to Joe public either... but I'll try and make myself sound like a pro. Lol. The stuff I've found is at local hardware stores. I have a few other places I can check out, but otherwise.... if my pro approach fails, I'll need to order online I guess.
Just a question about your burners, the burner flare, I've seen Bell reducers, stainless, black pipe unions used, what would you suggest? I had planned on machining a 3/4" union down inside the end to create the 1-12% flare. And to asnwer your question the interior space will be around 650 cubic inches.... that said would 2 x 1" burners be overkill or should I stick to 2 x 3/4" burners?
