Hello Ray,

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.

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
