Refractory wool forge liner also is known as Inswool or Kaowool. Rated to 2600 degrees F (1427 C) and 8 lb density. High-quality Ceramic Blanket Fiber Insulation utilized in forges, kilns, and tempering ovens. It comes in a standard 24'' WIDTH and sold by the LINEAR FOOT. (Each linear foot is 2 ft sq. because the rolls are 2 ft wide).
Sold in pre-cut lengths, or full box:
#1 Tip: Apply our Ceramic Refractory Paint (ITC -100) to your wool or brick.
Our ITC-100 greatly increases heat reflection, liner durability, flux resistance, and forge efficiency (by up to 40%). Stable up to 5000 Degrees, it also has a health benefit by preventing wool fiber from becoming aerosolized. A little goes a long way, and our pricing is remarkable.
Metaphorically: ITC 100 does to a propane forge what a turbocharger does to a diesel motor - it's like free power and efficiency.
#2 Tip: Use wool rated @ 2600 degrees (no less!) in your Propane Forge.
Propane atmospheric forges have a theoretical combustion temperature limit under 2600 degrees (would increase if someone started cutting the propane with acetylene). This is important because wool heated above its rating becomes aerosolized, and is not healthy to breathe (think asbestos).
Note: Wool rated at 1800, 2200, or 2400 degrees will LOOK the same as our 2600 degree wool and is fractionally cheaper, but I strongly recommend against its use at welding heats.
#3 Tip: 1" Wool+ Rigidizer is our best-seller but we also stock 1.5"& 2."
While most forges use a total thickness of 2" of wool, the majority of people double up with TWO layers of the 1" blanket in order to make fitting within tight spaces and around curves easier. It also allows you the option of replacing only the exposed 1" (half thickness) of the blanket.
Applying our inexpensive spray-on Rigidizer stiffens up the wool blanket, and makes it is easier to apply ITC-100 Ceramic Refractory Paint.
