Nathan Posted March 27, 2011 Posted March 27, 2011 Anyone know if a person can use clay as insulation in a blown forge rather than Kaowool? Quote
kcrucible Posted March 27, 2011 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. Quote
ThomasPowers Posted March 28, 2011 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
