Titanium coloring

Hi Priscilla, I have been playing with Titanium and Niobium and can
easily get all the colors of the rainbow by this method:

  1. I purchased the Anodizer from Reactive Metals.
    http://www.reactivemetals.com/rmsmini.htm It is sort of expensive and
    I have found several articles on how to make one yourself, but I
    opted to buy it.

  2. Using the Anodizer, I hooked it up to a digital voltmeter so I
    could tell exactly what the voltage it was putting out.

  3. I took a strip of Titanium about 6 inches long, and hooked up one
    lead (the negative lead I think) to the strip, and hooked up the
    other lead to an alligator clip.

  4. To the alligator clip, I hooked up a very small artists paint
    brush, by connecting to the metal ferrule that holds the bristles.

  5. I dipped the paint brush in my pickle jar to get a little acid on
    it for conductivity, turned up the voltage to about 10 Volts, and
    painted a stripe across the Titanium strip. If it didn’t react, I
    turned up the voltage a little more until I got the first indication
    of oxidation, which was a faint yellow coloring. I used a black fine
    magic marker to label this line with the voltage it took to get this

  6. Then I raided the voltage by .5 volt, moved over about 5 mm and
    painted another strip, which gave me a darker yellow. I marked this
    line with its voltage.

  7. By the time I got to the end of the strip, about 40 volts or so,
    in half volt increments, I had gone from light yellow, thru pink and
    purple , to dark blue, to a bright iridescent blue.

I did the same thing with a strip of Niobium.

Now, when I want a particular color, I look at my strip, crank up
the voltage to the color I want and paint away. You can paint any
color right next to each other, or raise a previous color to a
higher voltage and color.

If you go to far and want to backtrack, buff or sand off the
oxidation, and start over again.

Love and God Bless
