kcrucible Posted March 27, 2011 Share Posted March 27, 2011 Anyone know if a person can use clay as insulation in a blown forge rather than Kaowool? Clay, by itself, has virtually no insulative value. Mix in sawdust, cotton fibres, styrafoam beads, etc, that can burn out and leave air pockets, and you'll have rudimentary insulative firebrick.

ThomasPowers Posted March 28, 2011 Share Posted March 28, 2011 Of course you can use clay! Plan to make the forge walls Much Much thicker, Plan that your forge will take an hour to heat up to using temp and many hours to cool down to "safe" temps. Plan to spend *many* times the cost of a kaowool lining in wasted fuel. Can you tell us *why* you want to do this? Quote Link to comment Share on other sites More sharing options...
