Hi, i recently bought a cast masters smelting forge and trying to insulate it with the ceramic fiber blanket. I applied rigidizer first, heat treated it like the instructions stated and it became like stiff cardboard layer then applied satanite refracyory with 2 coats but each coat is cracking. I wanted to use itc 100 for the last coat but i dont know if i should scrap this and start over and maybe use fiber board instead of blanket. I believe its cracking because the blanket is able to flex but dont quote me. I just need some advice. Thank you.
