Sulphur staining a keris Bugis

Nice result and very nicely presented. Thanks!

Very interesting, thanks! The "sweet" smell of rotten eggs and the black colour of the blade are indicating the production of hydrogen sulphide and iron sulphide on the blade respectively.

Thank you everyone

Jean - thanks for sharing that. Now I am curious as to whether this would work without the salt and/or the starchy water.

Alan - yes that was my experience too. The staining stuff was pretty sticky and caked onto the blade.

I would be interested to do the same thing on a blade that is less grainy and porous as this one. But at the moment I don't have an appropriate candidate.

Hello Jaga,
I don't know but probably not.

I tried this method with one of the very first kerises of my collection, more or less 35 years ago. I started with a Bali Keris with an almost undiscernible pamor and an uniform light grey colour. After one week treatment and a terrible smell all around, I found that the iron was corroded, while the nickel of the pamor was left intact and in relief, in great contrast with the blackish iron.
The result was good and there was no need to make further treatments to the blade, except rinsing and oiling. I have somewhere the pics taken before and after, shall publish them soon.

The "hilt" in the second pic is not a keris hilt.
