Flint762 Posted March 17, 2017 Share Posted March 17, 2017 When using ceramic fiber board for a forge what is the minimum thickness that it must be? I have a 24 x 18 x 1 inch board and I would like to make a single burner forge. I was going to use a 1.25 thick hard fire brick for the floor of the forge. Can I use the fire brick the back up the board and will the 1 ich board stop heat transfer to the brick and outer walls? Thanks Flint762 Quote Link to comment Share on other sites More sharing options...
