We have a bunch of ceramic fiber blanket that we got from an old fiber kiln. I want to cover the arch of my kiln with it to seal and insulate it better. I want to cover the blanket with a layer of castable refractory or other suitable coating to create a shell over the blanket (think M&M’s). It is an updraft kiln, so part of the driver here is to keep particles/pieces of it from separating in the strong winds we get and blowing into the kiln. Also want to have the finished product to essentially be one piece.
I would love to hear from anyone who has experience with this process and their recommendations for the materials that should be used.
