Ok i think you covered the ceramic blanket with fire cement, Or Some other coating. Well i need too coat my ceramic blanket secondary burn chamber on my water boiler, due too i can feel the ceramic particles floating around the the heating stove areas. The next ceramic blanket stove or gasifier is getting coated on serface before it go’s intoo Use. too keep the particles from migrateing around, Hope its not as deadly as esbestes. Works good at keeping the heat in though.I am coating the one im useing before next winter.BBB.
