Quenchcrack, if i understand your answer just molten salt will allow you to temper. when i say just molten i mean salt that has heated to the fluid state. that said i would prefer to heat a heavy piece of plate to the tempering temp and then introduce the blade to the "stove top " cover with ko wool and alow to temper that way. and yes i have taken you advice and am trying to avoid the use of salts. As far as joining the HABA i havent thought of that and i thank you for the invite. Please be advised i am verry new to th feld of blacksmithing and am learning from a blacksmith down in SantaFe and we both are learning to make blades
