How did Empus obtain steel?

The Pamor on this Balinese Keris looks like it was made of some kind of crucible steel, although a metallurgical analysis is needed to be sure...

I red an article from a Dutch scientist visiting one of the islands (Sulawesi?) and describing that there they were making crucible steel. They used the material for their plows.
I cannot find the article but will look further for it and post it as soon as i find it.

Furthermore there is an article that describes the way of making iron/steel by the Dajaks.
They put a layer of charcoal on the bottom of their furnaces. On this way they add carbon into the bloomery iron and can make a kind of steel.

This seems unlikely to me Tatyana. Pamor is generally not steel. The word literally means "mixture" and it is generally a mix of various iron ores with varying ferric and/or nickelous content.

This is worth a read:-

Wow, brilliant find Alan, thanks!

Got lots of these papers David, both online stuff and hardcopy.

There's a good one done by an Aussie team, but I forget the details, it might be in hardcopy, not online, don't have time to look right now.

edit:- Land of Iron, Bulbeck & Caldwell

This is actually an archaeological investigation of settlement related to Luwu, but included in results is mention that iron smelting in Luwu might have begun as early as 600CE, and was certainly under way between 1480 and 1630, they hypothesise that most of the production was exported to Jawa and talk about use in keris & etc. In any case this work supports the fact that iron was imported into Jawa.

For anybody with an interest in this sort of thing, a good place to start is probably "The Bronze-Iron Age of Indonesia". van Heekeren

The folly of the Dutch in laying good raw materials on the ground that could be used by the locals was repeated elsewhere by the British. Railway tracks were used in India and Burma for making steel tools and weapons, and the Naga were known to appropriate plantation tools to create their dao. The Burmese also used anchor chains as a source of high quality iron.

Resourceful folks.

Not about keris, but while we are in this topic, I think I'll include this discovery as well.

Iron smelting site in Peninsular Malaysia dating 3 - 5th CE. Artifacts that had been found include 1.7 tonne of iron slag, 800+kg of iron tuyere and 150kg iron ore.

Research paper entitled "THE ANCIENT IRON SMELTING IN SG. BATU, BUJANG VALLEY, KEDAH"

http://www.cuhk.edu.hk/ant/Postgradu...kmaMOKHTAR.pdf

The following is a documentary about Sungai Batu. It is in Malay, but it have a reasonable English subtitle.

Very interesting as this civilization is actually older than Angkor Wat where some sites may go back as old as 500BC. 2500 years old.
