Ceramic Fiber Blanket, (2600F, 8# Density) (1" x 24" x 25'), High Temp Insulation for Ovens, Kilns, Furnaces, Forges, Stoves, Fireplaces, Glass Work, and Chimney Insulation

After seeing the 1-star review, and having ordered this myself before coming back to re-order, I feel I should counter that “dangerous misleading (or misinformed) review. First off: ALL ceramic fiber products are “dangerous” to inhale the dust when installing — but so is fiberglass insulation blanket. Simond store even gives you free gloves and a dust mask with the product. If you’re buying ceramic fiber for use in this temperature range and you don’t know that you should wear that included mask… then pump the brakes on your whole project and educate yourself on ALL of the safety risks involved in dealing with the extremely high temperatures in the 2600°F range this is used for, because you clearly need to inform yourself before you risk personal injury or property damage… due to the sheer heat you’re working with and the need to properly contain it with this type of high-temp ceramic fiber insulation. That super-basic safety is YOUR responsibility.Secondly: this ceramic fiber blanket is made from aluminosilicate with added zirconia to achieve the 2600°F temp rating. It’s literally the safest type you can buy that will retain insulative properties in this temperature range. (Plain aluminosilicate ceramic fiber is only good to 2300°F) The only other option for 2600°F is chrome-aluminosilicate — but chromed “kaowool” will offgas chromic oxide fumes if you happen to exceed its temperature threshold, which is toxic. THIS product, however, does not have that risk. It might thermally degrade and disintegrate, but it would not release fumed chrome compounds into the air, soil, and watershed, which is neurotoxic and persistent in the environment where it’s released. This zircon-based ceramic fiber is a great product and completely safe when handled responsibly, with no need to worry after it’s installed.

Lined my forge with this and it does an excellent job of retaining the heat making forging easy and fast.Great quality and economical.

There were no consumer warnings enclosed. Good thing we looked it up.
