Archaic kris for comment

[xasterix]

Hullo Milandro! Sorry it took me a while to get back. I didn't FeCl the kris anymore. As chance would have it, I was able to contact a descendant-relative of the original Maguindanaon owner, and upon realizing the value of that pusaka, they expressed that they would like to acquire it in memory of their ancestral lineage. As much as I want to keep it (who won't want to keep a twistcore, right), out of goodwill I let them acquire it from me. That's one less twistcore for me, but at least a family reclaimed its pusaka.

Anyhow- I've been experimenting a bit, and my current preference is a mix-
1. Mirror polish then FeCL, stabilize
2. I immerse a white vinegar-filled tube with old brass for around 2 hours
3. I dip the blade for around 30 mins (as a second etch), stabilize

So far I'm pleased with the results. It doesn't show up that clearly in my pics, but there's a golden tone to the etch in certain places (due to the brass residue). Here's some pieces I did that progression with.

Hello Xasterix,

thank you very much for getting back to this thread with such relevant information and very well done for returning the acquired kris to the family of the original owner. You are a gentleman.

Anyway.

Thanks for sharing your experience and your personal recipe.

I am considering all options for my one Moro blade (which I did publish elsewhere in another thread but I can add a picture here for completeness of the discussion).

I don't think it has a twist core or any other major feature , yet, I think that giving it the chance to show the hidden secrets (so to speak) may be a nice touch.

I am going to consult a local master bladesmith , hoping that he can provide some insights from a " de visu" exam of the blade.

Thanks for the kind words Milandro! I'm betting that your kris is laminated, and that the hardening at the edges will be marked neatly once it's etched (as to how dark, light, or contrasted, that'll depend on your etch media and strength). Good luck, and let us know how it goes!

Hello Xas,

Be careful with your blades, I see brown corrosion by your kris, this is what Kai mentioned before about etching with FeCl.

Detlef

Hullo Detlef! Thanks for the heads-up- but that's no corrosion don't worry- it's the "effect" of etching with white vinegar + brass residue =) it gives a different tinge to the etch which I fancy (but I understand it's not for everyone's aesthetic). Here's some more pics.

It’s honorable of you to have the Maguindanaon family have their Pusaka back.

What’s the purpose of adding the brass to the vinegar?

Thanks sir Albert =) oh that's just an experimental mixture of mine to add some random brass-ish color to the etch. I noticed that brass, when soaked on white vinegar, leaves residue. It's etched unto any dunked blade afterwards. It's easy to lighten up or remove with some fine steel wool.

It also affects the color of other metals, including silver I think- notice how the asang-asang became gold-ish, same color as the etched residues on the blade.

Hello Ray,

It looks like you're essentially electroplating the copper from the dissolved brass onto the asang-asang.

On the blade, your results still do look suspicious to me. When I've seen effects from "contaminating" metals/alloys, the "deposit" seemed to be much more evenly distributed - at least if the blade was regularly moved in the etching solution to avoid erratic results.

Kai

Thanks very much for providing me with the formal term!!! The problem was that I did not regular move the blade in the mix, hence the erratic distribution.
