Anodizing process

 I can't wait to try this anodising my mesh as soon as we are allowed back at campus. Ganoksin has a tutorial on how to do aluminium anodizing. My process may not be exactly the same as the article but I summarised the notes and attached the diagram of the process below as a starting point.

Tisdale, D., (1985). Diagram B

Notes about Diagram B:

Caustic Soda- 113-170g of soda to 4 litres of water for 5-10 min

Nitric Dip-5-10% solution for 2min

Anodise-Sulfuric Acid bath of 15-18% solution at 21C, with a positive current at +/-12 volts

Neutralize- Baking Soda and water solution

Dying- cool dyes and short anodizing time for pale shades and hot dyes and longer anodizing time for darker colours

Seal-boiling water with Sandoz Sealing Salt for 10min

Do not touch the aluminium surface until after it has been sealed as the porous surface is susceptible to dirt.
