    Instead of heat treating you can anodise titanium with cola and a DC supply.
    The more voltage you put through it the more the colour changes.

    I've seen that vid, Vapant. if I had a titanium mod, I would definitely try that. Seems much easier than aluminum anodizing.

    I found another pic of the new nemesis mod. From what I gather, this uniform color is from some kind of heat treatment in a kiln or oven. Temperature or length of time in the oven seem to determine the color. For instance, you might put parts in there until they just barely glow for a second then take them out and they would be uniform blue every time that way.

    Thanks a million. I love the way it turned out. Just wish I had a ss tube for it so I could make it look a little more uniform. I think the stock tube looks sweet now though.

    If a Mac 350 is heat treated , can it be brought back to original color?

    I think what you will find is that Different Temperature yield Different Results. But also, how clean the Metal is Before you Heat the Metal.

    Try doing a test piece that has been Oiled Lightly. And then try doing one that has been cleaned with Acetone.

    You also find that Different SS Alloys will yield Different Results. Remember, Stainless Steel is a Family of Metal Alloys that contain Both Chromium and Nickel. SS is Not a Singular Metal Alloy.

    The Exact Percentage of Chromium and Nickel is Debatable. But many don't consider an Alloy to be SS unless it has At Least 13% Chromium and 3% Nickel.

    BTW - The percentage of Chromium will Rarely Exceed 20%. Because after 20%, Very Few Benefits of adding Chromium are seen.

    Hmm, I might have to pick up some Ti pipes and try the soaking method with voltage

    When anodizing titanium, a thin layer builds up on the surface of the titanium and reflects light causing us to see color. The colors change based on the thickness of that layer and the amount of voltage applied to the titanium. I am sure the exact same thing is occurring when we heat treat SS and titanium mods. The torch/heat creates a layer that reflects light resulting in color. These layers are often very thin especially with anodized titanium that was done at low voltages. The finish can be rubbed off and eventually re-done, or it can be covered in some kind of protective clear coat.

    There are color charts for titanium and SS out there to find out how much temperature/voltage to use to get a certain color. But as zoiDman said, The exact color obtained when performing these techniques can depend largely on the piece that is being treated.

This is pretty advanced stuff from what i gather.

    Here is the knife I'm talking about. It's titanium, but I think its possible with SS as well. Imagine a PV like this:
    That is Chad Nichols Moku-Ti. It's $950 per foot of 1" rod. I order SS Damascus from him all the time. It's brutal to work with but comes out nice. Also Moku-Ti is etched via chemical....it's called multi etch.

    I think that treating titanium with nitric acid acid bath will etch and leave a gold tone. I know thats how my lady's titanium gold bicycle chain was done...

    For aluminum body mods, google colored home aluminum anodizing. There are kits for a hundred bucks that can do bicycle and car parts, wouldn't be hard to dip a mod body in there either. Purple eVic? Hmmm... I have a couple of silver tubes to play with *ponders*

    If you want to play with anodizing I have everything you need I'll almost give it away minus the power supply..........pm me.
