Review on Ceramic Fiber Blanket Fireproof Insulation Baffle - 2400F Rated, Heat Resistant for Stoves, Kilns, Forges - 1x12x24 inch by Carrie Spencer

I used to insulate a small toaster that I use in the shop to bake stabilized wooden knife shells. 1" was too thick for my needs so I was able to separate it neatly into two 1/2" blankets. Be sure to wear a long sleeve shirt, disposable rubber gloves and N-95 respirator, this material will scratch and leave small particles. when you cut and shape it. Wash your clothes separately and shower afterwards if you don't want to be itchy all day. Very similar to old mineral wool if you've ever worked with it. Should make my toaster's temperature more stable as it only had air as an insulator prior to installation.
