Yes, David is correct .

This color change is located about where a sepuhan line would appear .

Def. not rust .
Pamor ?
Something kind of like uler lulut; but what's in a name ?

I have seen FECL also do the same browning thing to certain ferrous metals .

Before .....

Thank you David and Rick.

Rick, what do you mean by FECL, I assume that it is ferric chloride or FeCl3? Ferric salts have indeed an orange color.
By the way I have one blade from Lombok with a golden shade on the pamor and do not know the origin.
Best regards

I never did well in Chemistry .

hmm orange..

Fecl3 thought it was bit grey/pinkisch and with O2 contact becomes brownisch/black...... And FeSO4 is green isnt it???

P.S. the orange/redisch one is K3[Fe(CN)6]Potassium ferricyanide

EDIT>>> FeCl3 Hexa Hydrate is orange coloured.....I missed that one.. my appolegies

Other FeCl3 salts are grey to black

Have a friend in Germany who is involved in cancer research. I think that he uses arsenic trioxide. If you know someone in that field, locally, they might have some ideas about where and how to obtain it.

I once contacted a chemical supply house that offered to mail some to me, but they had to deliver to a commercial location.
