Source of Ceramic Wool OR Kiln Bricks
I am reposting this here, maybe someone here can help me find what I am looking for.
I am looking for a source of small amount Ceramic Wool (??500 mm x 500 mm??) OR Kiln Bricks (4-8) in Melbourne to aid heat retention /deflection for a small heat treating forge?
I am making some small hand tools (Crooked and Chip Knives) from O1 and need to heat treat them. I have all the heat source sorted, (4.7 Lt LPG tank, with fittings, hose, handle and nozzle).
My reading however tells me that if you are doing anything more then 3 mm thick then you need some form of heat insulation.
Can anyone point me in the right direction?
