  1. I built a gas forge a few years back out of a pearlite insulator, but I never put a refractory coating so it began melting pretty quickly, I ditched it and made two solid fuel forges some time later but recently as it got colder I decided to work on my propane forge so I could work in my dads shop. The forge is a cylindrical stainless steel can with a pearlite insulator (I forget the exact recipe but I think it was something along the lines of a pearlite aluminum oxide mix) When I came back to the forge I had more knowledge so I acquired two pounds of satanite and installed fire bricks in the base and sides for better structural support and insulation. The Satanite bonded to the firebricks very well, but when I thought everything was going well on the second coat almost half of the satanite delaminated from the pearlite ceiling. In the end I lost pretty much all of my satanite and ended mixing the leftover slurry with firebrick and pearlite "mud" as a temporary patch for the exposed section of the ceiling. I don't really have any confidence that the temporary patch will hold the heat terribly well but I cant see many alternatives with my limited supplies. What refractory options do I have, and what materials would be best to fix my problem? (I don't have much cash but I could spend a bit if I need new materials) (Note: I'm having trouble uploading a photo to the topic, I tried to describe what I could but if anyone knows what the problem is I could post a few pictures.)
  2. Hey everyone I'm new here. I want to start by saying I've learned a lot already. That being said building the ole first forge and I have not seen a ton of info about combining insulating methods. I was going to try pearlite and refractory to close the cavity in my 22 propane tank. Then an inch fiber blanket soaked in sanite. Once hardened coat with cement. Just for knife making maybe forge welding down the road. Not sure I saw this combo anywhere. Is the pearlite all bad news? I heard it can sag.
