Anographics is a Silicon Valley, Ca. based company dedicated to the art of anodized aluminum. What are Anographics, simple put, Anographics is a thin plate of aluminum prepared to absorb dyes much like a piece of paper but with much more diversity of coloring techniques and brilliance of color, not to mention longevity. Humidity and temperature will not effect Anographics. All traditional artist techniques are employed with many inherent only to the anodizing process, plus a number of surface finishes can be used. The combinations are endless. For the artist who likes to be on the edge, there is nothing quite like it. Technically speaking Anographics are anodized aluminum. Anodized aluminum is an electrochemical process that converts the metal surface into an anodic aluminum oxide finish. This finish is not on the surface like paint or plating, but actually becomes fully integrated with the aluminum substrate. It has a highly porous surface that allows for the absorption of many different types of dyes. Anodizing occurs by immersing the aluminum into a sulfuric acid electrolyte bath and passing an electric current through the metal. A cathode is mounted on the inside of the tank, the aluminum becomes the anode, the opposite is true for plating. Oxygen ions are released from the elec- trolyte to combine with the aluminum atoms at the surface. Anodizing is therefore a highly controlled aluminum oxide coating, which is a naturally occurring phenomenon with aluminum. |
