Etching wootz, opinion needed.

I will only add one more thing - Turkish wootz does not pop out like Persian or Indian wootz. This pala might be Turkish wootz.

I think I might know why coffee gives dark black wootz lines.
Coffee is acidic and oxidizes ( rusts) areas with higher content of carbon. But at the same time it contains tannins that convert rust into permanent black Fe tannate.
This is similar to the so-called "rust converters".

Yup, that would be my understanding as well, Ariel.

So the more coffee I drink the darker my insides get?

I'm not worried about that. There will be a wonderful wootz pattern on the insides
