Anodizing is a type of surface treatment that can be done to certain metals like aluminum and titanium. Using an electrical source and a sulfuric acid bath, a microscopic layer of oxide is 'grown' on the surface of the metal.

With aluminum, this oxide layer not only provides abrasion resistance, but the layer can be colored with a vast array of dyes and masking techniques.

Once the dye is sealed into the oxide layer, the coloration becomes highly resistant to solvents and harsh environments, making this a very durable way to finish aluminum.

Using surface treatments like polishing, hammering, mill rolling, sandblasting, and etching in conjunction with anodizing provides an almost endless array of potential effects.

Interested? The class will consist of:

• A brief lecture describing the process and showing samples of what effects can be created and the techniques use to achieve them, then we'll head to the workshop and get our hands dirty with:
• Etching, hammering, and other surface finishes to apply before anodizing
• How to properly prepare your parts for anodizing with the cleaning and etch baths
• Using the anodizing bath itself (safety first!)
• Rinsing and dyeing parts
• Sealing parts after dyeing
• How to use masking and bleaching to selectively color the metal
• Playtime - once you see how the process works, and how different effects are created, you'll be eager to begin experimenting and develop your own techniques: “There are no mistakes, only happy accidents.” – Bob Ross
