3170 Ceramic Fiber Paper 1/8" Thick, Size 11" x 12" 10 Sheets, High Temperature Insulation Gasket or Liner Paper for Kiln Stove Furnace Glass Fusing

It’s fiber Fox and it worked well.

Exactly as described

Made a perfect gasket for my Atwood furnaces exhaust

Cuts well, seals well as a gasket, insulates well.

I needed a new gasket for the pellet stove. went to the place where I got it stove! they had none in stock. they said it might take up to two weeks to get one I ordered this stuff from amazon ,had it in a few days! it was so easy to cut with a razor and it gave a nice tight seal!!!!

Used to set glass blocks on in kiln when firing on glass paints and frit. Used couple times to 1225F, so far great. Don't paint with kiln wash, that stuck to glass block but was removable. Ceramic fiber paper allows glass to cool faster as it is not sitting directly on kiln shelf.

I purchased this product to line the inner floor of my oven (not inside the over itself, but between the sealed bake element and the oven floor.The description says the ceramic fiber sheets will insulate up to 2300F. After I installed them, I set the oven to 350F as a test. Within five minutes, there was smoke pouring out of the back panel of my oven. I sit everything down and turn off the breaker. After the oven cooled, I removed the fiber sheets - they were charred and had fallen to pieces.I will never purchase from this seller again. What a waste of money, time and effort.

Nice and dense - good quality - bought twice
