Spear head to identify

Great job on the etching the Indonesian spearhead Thomas.
I've never heard of etching with instant coffee until now. I had to google it and found the process.
In your experience with it, how does the coffee etchant react with copper or brass?

Thanks for sharing.

I have no experience with etching brass or copper because I etch my blades before assembly. But a good question. I have some pieces of my own mokume gane ( brass and copper) on the workbench. I will try and post.
