Glenn Posted April 12, 2019 You will need 2 layers of 1" 8lb. ceramic wool refractory (a high temperature insulating layer made from ceramic fibers) such as Inswool insulating blanket. It is best to use two layers of 1 inch material rather than one 2” layer. Measure the circumference of your forge subtracting 1/2 “ from the diameter (half the thickness of your wool) and cut ever so slightly large. This will create a fit that is tight enough to keep the wool rigid in place. Before adding the second layer, rigidized the first layer and burned off the water with the burner. The color of the dye faded to white as the wool heated up. When it was basically gone stop the burner. It can take about five minutes, maybe a bit more. The second layer is added using the same math measuring from the new, smaller diameter created by the wool. Quote Share this post Link to post Share on other sites
Utahusker Posted December 14, 2019 If applying two layers of 1", is it good practice to apply rigidizer to the first layer before putting in 2nd layer? Quote Share this post Link to post Share on other sites
Frosty Posted December 15, 2019 It isn't NECESSARY but it doesn't hurt. It will stiffen the insulating outer refractory a little more and so make a more stable surface to support the hard refractory inner liner / flame face. This is discussed in depth in the Forges 101 thread. Frosty The Lucky. Quote Share this post Link to post Share on other sites
