It's the same old story

Rick,

The chemistry teacher made the sulphur acid solution for me. She used concentrated sulphur acid and distilled water. I did it in the chemistry room next to the classroom at school. Some students came to take a look at the process from time to to time with the permission of the teacher. It became an educational project as well. The solution was as strong as the sulphur acid in a car battery. It was 20 or 25%.

And yes, even after washing and oiling that lovely stink of the sulphur came into your nose. I just left the blade (it was a worthless one after all) a few weeks in the garage. Now it is in a box on the attic in the garage. Didn't look at it for ages.

Henk, that was an etch with sulphuric acid, not a stain with sulphur.

You can get some sort of a result with just about any acid, nitric is probably the best result from an acid, but its horrible stuff to use, and I would not recommend it.

The sulphur stain job that I did years and years ago was powder sulphur mixed to a paste. The description in the book called for it to be wrapped in a banana leaf, but I wrapped it in plastic.The process took about a week.

I've had a look for that book, but its not in my book cases, which means it is in a cardboard box in my garage. I forget the name, but it was by an Englishman, it was an Oxford University Press reprint, and it has red dust covers.I'll locate it one day.

Well, I had at the Ganja Iras with the Ferric .
It took a couple of tries and the effect may be the reverse of what it might be if traditionally stained ...

I just wanted to see the pamor .

It seems a bendo segodo/uler lulut pamor.....but....it's like a negative picture!!

That's what I meant to illustrate; maybe the positive effect shown ( see bottom picture) would be caused by Arsenic .

With Arsenic the iron goes black instead of the result I got with ferric .

I see uler lulut (albeit a loose one) Marco .

Of course if this keris is Balinese the pamor may be called differently there .
