This simple guide describes how to anodize titanium. Colorize sheets of titanium to create permanent, metal artwork. Titanium is valued for its weather resistance and durability, but it is also valued by artists for its beauty and colors when oxidized. All it takes is a thin, transparent layer of oxide to create color on the surface. This process of wave interference occurs when light reflecting off of the coating collides with light reflected off of the titanium surface.
Coat the titanium in phosphoric acid (cola will do). This is easily done by filling a paint roller's pan (or a shallow tub) with cola, then dipping the titanium into the pan.
Attach a wire to the titanium with a clip, then attach a battery (or multiple batteries) to the wire.
Attach another wire to the paint brush, then attach the same batteries to this wire. It does not matter if the batteries' positive or negative terminals is attached to the titanium or brush, as long as current flows in one direction.
Fill a jar with cola, then dip the paint brush to coat it in cola.
Experiment with various voltages to achieve different colors
