I am a newbe to forging. Up until know I have been using stock rolled/machined steel ( O 1) by stock removal and quenched in used Olive oil. I use a temperature controlled kiln. These are specialty knives for wood carving usually 1/16 to 1/8 inch thick.
Now I am teaching myself forging. I have no experienced blacksmiths close that I can learn from. I bought a gas forge and an anvil. Steel is used steel from a flea market. Files, saws, etc. I intend to go on making full size knives.
My questions are: what oil do I use for quenching? Is Olive oil OK? If not, automotive oil? Buy new oil meant for quenching?
Does quenching oil go bad?
HELP.
