process for anodizing aluminum with limited equipment?
So first of all, do I need sulfuric acid? Any substitutes? Will HCL work, or a weak acid like vinegar or even salty water? If the purpose of the sulfuric acid is to allow free ions to flow in the water, I do not see why it would not work. However, I am not a chemist, and my experimentation with electrolysis is limited to 6th grade science and dropping 9V batteries in salty water. (My favorite experiment was at home when using copper and coins as the electrodes and watching blue-green corrosion develop and sink until the copper wire was made brittle and thin. Caused some AA rechargeable batteries to explode in the process though lol!)
Also, will any die work? For really small parts, will it be possible to evenly die them with sharpie, standard paper markers, and/or highlighters? What dies will work well? Should the dies be water based, or based on some other thinner?
