I have recently been reading about an old technique call Super Quenching
for hardening low carbon steels lie 1018. The claim is during testing the
consistently got hardness over 40 with occasional test pieces testing as
high as 48.

In the reference I ran across the want to have us mix up five gallons of
quenching liquid.

If anybody has used this technique I have two questions for you.

1. If I keep the proportions right is there any reason not to just make up
one gallon?
(I only need to harden one part.)

2. How hot do I need to get the piece before quenching? Straw? Dull Red?
Bright?
