Aluminum does not rust, nor does it take a patina with the standard chemicals normally used to darken jewelry. It oxidizes the moment it comes into contact with oxygen or water! Fortunately this oxidized layer of aluminum oxide (Al2O3) immediately forms a stable layer that protects aluminum from corrosion or further oxidation (as long as it isn't exposed to chlorine or similar substances that are corrosive to aluminum). Do not use with Win-Ox™! So how do you color aluminum? Bright, permanent colors on aluminum are achieved through anodizing. Anodizing is an electrochemical process that converts the metal surface into a durable, corrosion-resistant oxide finish. Although the color is durable, aluminum is a soft metal. When working with anodized aluminum, take care to avoid scratching through the anodized layer. You can also use paints, Ranger alcohol inks, and Vintaj's faux patinas, but we recommend avoiding traditional jeweler's chemicals, which are intended for other metals.

24-gauge, 6x6" (approx. 150x150 mm) sheets of anodized aluminum sheet can easily be cut with shears, and used with punches to create shapes. Add holes wth a drill press, or use hole punch pliers or your favorite hole punch tools. The colors of anodizing can vary from batch to batch, so slight differences in color are normal, and not a defect. Try stamping or engraving this brightly anodized Marmalade orange metal for interesting results. Works great with the Sizzix and Vintaj DecoEmboss and DecoEtch dies! Do not use with Win-Ox™.
