I have an empty freon tank that I would like to make a forge out of. I have seen many people go with the Kaowool/Satanite/ITC-100 layers to create the forge walls. Has anyone tried to just pour a castable refractory cement like you would in many of those coffee can forge instructions? Or would this just make it an overly heavy forge. I am looking to step up from my firebrick forge so I can have something with a large diameter, I am kind of stuck at a max 2" right now.

Thanks.
 
I'm no expert but it think it has more to do with thermal mass

As is in takes more fuel to get the solid cast one up to heat vs the one made with kaolin wool

The wool provides the bulk of the insulation whiles the cast helps with melted Flux.

The itc-100 is just a super heat reflector that goes on real thin (expensive)


If your making a forge strictly to do billets in and you know your gona have Flux every where then it might pay for it self. But I think peeps build the vertical forges for that

Like I said I'm know expert just a fledgling maker that's not making right now lol
