My adventure of watching aluminum age... zzzzz.... This is really just a post about something interesting I've been doing. Not a question thread or whatnot, which is why its in this section. ____ I have been using aluminum rings to make small pieces of maille armour. The rings are very polished, because they need to be smooth so they are comfortable to wear. However, the process also makes them very shiny... so shiny that they do not at all resemble steel or iron, which I want it to. I don't use steel because I am not a strong person and this maille is for costume, not combat (light weight is good). I have experimented with various methods of ageing the rings so it is duller, to resemble steel. They all involve placing the rings into a container filled with some sort of solution. The best method that gives it a nice aged look without damaging it at all is to use sodium acetate dissolved in 3% hydrogen peroxide (I did a side by side test of the acetate and acetate with H2O2, and the one with H2O2 completed hours ahead of the other). So if any of you want to dull aluminum for whatever reason, the best result is using sodium acetate, not vinegar like everyone else says. All the websites tell me to use vinegar, but I have done numerous trials with my armour, and vinegar seems to leave a white crusty residue that will not rub off, which, if the aluminum is touching anything at all, is not wanted. I thought this was kind of interesting. I can also give you people pictures once I finish something (I have simply been experimenting with my maille techniques so far, and only made a small chain square).
