http://TitaniumRingsForever.com and Chris Boothe demonstrate the coloring of titanium and niobium through electrical anodizing. A process combining science and art, it is used in the creation of titanium wedding rings and other titanium jewelry. When electricity is used to create colors on niobium and titanium, the process is called anodizing. During anodizing, the metal is immersed into an electrolytic bath through which an electric current is passed, causing an oxide layer to form on the surface of the metal. Light striking the surface of the oxide layer and the metal below will result in two refracted light rays which reinforce each other and produce different colors depending on the thickness of the oxide layer. This phenomenon, called optical interference, is responsible for holographic images and the iridescent colors in butterfly wings and soap bubbles. The colors are called interference colors, and were first described by Issac Newton in the 1670s.

Thank you for this great how-to.

Please
continue making videos on niobium techniques, like
masking, so that I can actually make pictures or
designs with color.

Hi Chris,
Thank you for sharing.
Could you
please tell me more about the AC to DC converter that
you are using, I am looking to purchase one. />Brood.

Dear Ski & Cathy--thanks so much for your comments.
We're thinking our next video will show masking
techniques. To get a specific color, you can either
set a particular voltage level, or set the voltage at a
high level and take the piece out of the bath before it
goes beyond the color you want. Any given color, say
yellow, is always the same thickness regardless of how
long you left it in the bath--doesn't get deeper. If
the oxide thickness continues to increase, the color
will continue to change. Thanks so much for your
comments.

Chris - Thanks so much for sharing your talents with
the rest of us. Your work is pretty special, and it's
certainly an inspiration to anyone who might want to
try anodizing. I was surprised to see voltage/time seem
to repeat some of the colors on the sample strips. I'm
assuming the longer times produced a "deeper"
oxidation. I would sure like to see the process of
masking and all other magic you do, although I
understand you can't reveal any trade secrets. From all
of us "lurkers" here on Orchid - thanks. />Rgds.............Ski & Cathy
