Thanks. It was a simple thing to do.. I like it. I am wondering if I can get it darker as well.Blues look good! That is a loooooong neck!
They make it sound complicated. Haha. I just torched it till it turned color. Lol..Prepare an appropriate heat source, such as a charcoal fire, a propane forge, a torch, high temperature salt bath or electric furnace. Ideally, the heat source will provide a uniform heat, be easily controlled and provide a non oxidizing environment.
Heat the steel to temperatures from 400 to 800 degrees Fahrenheit, to produce oxidation colors. At 480 degrees F., the steel turns brown, at 520 degrees, it turns purple, at 575 degrees, it turns blue and at 800 degrees, it turns grey. These temperatures are commonly used in tempering tool steel.
Heat the steel above 800 degrees to produce incandescent colors. From 1000 to 1500 degrees, the steel will turn an increasingly brighter shade of red. At the critical eutectoid temperature of 1335 degrees, the steel recrystallizes as austenite and eventually loses its magnetic charge. From 1600 to1900 degrees, the steel will turn orange and then yellow. At 2000 degrees, the steel will be bright yellow.
Remove your steel from the heat source and quench it vertically in oil. Once the steel is cool enough to handle, temper it as soon as possible.

I like the 650 color.. will have to try and heat it again..
Totally. Thanks!I just wanted you to see what colors you might expect and at what temp to get there.
There week be variations in color and temp based on exactly what the metallurgy/make up of your steel is.I like the 650 color.. will have to try and heat it again..
How do you like the Kronos?
what is the next step to improve? I kinda like the uneven look but I love how smooth yours looks as well.
Dang man. You have skill.600° part temp is your goal for a rich blue. I do it all by eye with a Map/Pro torch.
For best results, the head must be clean. And I mean CLEAN. scrub it with soap and water, degreaser, acetone, and more soap and water, and try not to touch it with your oily hands.
As you play with it you'll see that the less of a polish the more dull of a color you'll get. The best blues shine through on a mirror finish (see pics)
Here is a high buff (brushed, but still pretty shiny: )

Next up, bead blasted - fine grit

Lighter polish (notice how the color is more dull?)

Stainless is a completely different animal. My understanding is that with stainless, the color you are able to achieve has a lot to do with the amount of chromium in the metal. I've had some really nice blues in some, and others that have turned an ugly grey.
Love it! And love the Kronos! SO good!Motivated by seeing @Vosh68 torched M craft in the first shaft up. I tried my hand at it today.
took about 30 min and almost a full bottle of Benzomatic gas but I think it turned out pretty cool.
I may try and take to blue up the neck a bit more but I want to keep a bit of the two tone look.
