Tombak Opinions Wanted

Tim Simmons · 14th May 2006, 10:53 PM

I felt urged into this, it is a live experiment. The handle does not want come off and I am not going to pull it off. Now I have started I think I should go all the way, with guidance I hope

. I hope my pictures will be good enough.

I can already see that the blade is quite old and more pitted than I thought. The juice does seem to be reacting and making darker looking areas. If I wipe off the juice, it is at the moment a little more difficult to see the pamor/forging. However when I inspect the blade with a glass I think more interesting patterns are being revealed. I will carry on for a day or two, then come back with more pictures and attempt staining.

look at this now, hard to believe it is the same blade.
It has no patina

and although interesting rather harsh. I do not know how I feel about this

.
One side appears more patterned but this may change with staining. As it is now apart from the silver coloured patterns there seems three shades in the metal. I am glad this blade was no bigger, picking with a x10 loop and a dental probe is not the best way to pass time.
I am at you keris fans mercy where do I go from here? how long does the stain affect last?

Is that it then? Just oil it once in a while. I thought there was a special staining yet to do.

Oiling would be good unless you want to play with *arsenic* .

* which reminds me of an old joke about how the Barber killed his Wife with a rusty razor ...

Tim, this blade is well on the way to being clean, but it is not yet clean enough to stain.

Every bit of rust must be removed.

If you go ahead and stain in this half clean condition you may not get a satisfactory finish.

A 10X loupe is too high a magnification for the job of picking out the rust from the pits. I suggest you try a 2.5X, or 3X, machinists loupe. I find I can work with one of these for very extended periods. Another way to go is an illuminated magnifier, or a pair of magnifying glasses.

You can also attack those tiny remaining bits of rust with hydrochloric acid. Just a drop at a time, and wait while it works, then wash off, and possibly kill it. If you use the hydrochloric, follow with another day or so in the pineapple juice.

Do not be in a hurry to get this job done.

Seven to ten days in pineapple juice is about usual for a blade in the condition your blade was in before you started.

I once spent over six months, working most week nights for an hour or so at picking the rust out of the pits in a Bali blade. If you want a job you can be proud of, you must work slowly and carefully.

When you do get this blade clean, and if you decide to go ahead with the arsenic stain, give it a really good polish with steel wool and a powder sink cleaner before you start. The blade must be white before you commence to stain.

Regarding the metuk.
As a generality, a lower quality tombak will have a metuk that is forged as a part of the blade, not a separately made and mechanically attached metuk. A village quality metuk will nearly always have this type of one piece construction, or sometimes with no metuk at all.
It is not necessarily related to age, although most recently made tombak do seem to have the integral metuk.
Note that I am talking in generalities. It is entirely possible for an old, good quality tombak to have an integral metuk, however, this is rare.

Listen to me talking like an expert

. If I remember correctly from my old metalwork days, I was always told to keep the iron tongs out of the pickle as iron slowly neutralises the acid. Each day of the cleaning of this blade I changed the juice. I dare say one could take this further, but for the time being I am happy the way it is now. My conclusion on all this is that, as this sort of treatment is accepted and indeed expected in the objects cultural origins, it is okay to do so but to fiddle like this with old blades just because they are "East Asian" might make you a vandal!!!

Tim, its your blade, and if you are happy with it as it is, please forgive me my previous comments.

Changing the pineapple juice every day is unnecessary. I use the same juice from day one to day ten. In warm weather you can get some very interesting cultures on the surface of the juice. I have sometimes wondered if they might get up and walk away overnight.

I`m sorry, but I do not understand your "vandal" remark.

Can you elucidate?

Tim Simmons · 19th May 2006, 08:14 AM

If I carry on where do you get the staining substance that contains the arsenic and how is it used?

I only say vandal as a sweeping gibe at inappropriate care for antique objects, cleaning, polishing etc.
