Quenching Oil Question

[G2]

I'm newly on the journey of knife making and I would like to know what makes a good quenching oil for O1, 1095, or 1085. Thanks and regards to all.

For O-1, vegetable oil is supposed to be good. For the 1080 and 1095, I heard that brine quench works well. Mix salt into the water until an egg or potatoe will float and heat both the oil and brine to about 150 degree F. Hope this helps!

i forge O-1 alot and i like to use vegetable oil,but there are a lot of different choices like mineral oil ,automatic transmission oil , light weight motor oil , olive oil , and the actual quenching oil ,but if your just getting into it , just try some cheap vegetable oil....heat till the magnet doesn`t stick anymore , heat just a bit more then quickly quench in oil ,i temper at 375 degrees for an hour ...do that twice and voila 60 rockwell , then on hunting knives and knives that will see some abuse i put the knife edge in wet sand...about 1/3 of the blade width is in the sand,then heat the spine with a propane torch till the spine turnes bright blue and down by the edge is straw and there you are a dang tough blade as far as O-1 goes!! hope that helps..sorry for writing a book for ya!!

gees i for got some real good stuff...before you heat treat grab a coffee can fill 1/3 with borax ( the washing type ) then fill the rest with water bring to a boil,as it rolls to a boil dip your knife in there a bunch of times , then let dry.Once it is dry you can heat your veggy oil up to 130 degrees , very important to keep consistant on the temp , THEN heat the blade till the mag doesn`t stick + a little more then quench.
