What’s the purpose of adding the brass to the vinegar?

Thanks sir Albert =) oh that's just an experimental mixture of mine to add some random brass-ish color to the etch. I noticed that brass, when soaked on white vinegar, leaves residue. It's etched unto any dunked blade afterwards. It's easy to lighten up or remove with some fine steel wool.

It also affects the color of other metals, including silver I think- notice how the asang-asang became gold-ish, same color as the etched residues on the blade.

Hello Ray,

It looks like you're essentially electroplating the copper from the dissolved brass onto the asang-asang.

On the blade, your results still do look suspicious to me. When I've seen effects from "contaminating" metals/alloys, the "deposit" seemed to be much more evenly distributed - at least if the blade was regularly moved in the etching solution to avoid erratic results.

Regards,
Kai

Thanks very much for providing me with the formal term!!! The problem was that I did not regular move the blade in the mix, hence the erratic distribution.
