I decided to work from Skelleftehamn today, so that I will be able to return the new personal computer I had bought as soon as the shop opens (ok, as soon as I finish my meeting, which starts when the shop opens).
Why? In part because I didn’t much like the propensity of Windows 11 to do things for me without asking consent first. In part because my home Wacom pen and tablet is too old to work with that type of processor (it literally wouldn’t install the driver that works with that pen/tablet, as the “platform isn’t supported”), but the straw that really made It easy to decide not to keep it was when I tried to copy over the documents folder from the old computer, and it wouldn’t fit. Therefore, it wouldn’t be possible to install any programs, either. Nope, just nope. I will take it back, and put off buying a new one till after we get back from Boar Hunt.
After work we went to buy a ladder to fix the roof on the house, and then to the Museum for a lecture. Järnframställning i Norrbotten

Järn i norr
Forntida stålverkning bland jägar- och samlargruppar i Arktiska Europa
Carina Bennerhag
- Carina’s new research on how it spread and passed on to new generations.
- Iron work in north 2000 år sedan
- laste for Archaeologists to notice because still hunter gathering here
- Sangis 200 år f.c. stål verk
Vivungi
Found slag in two places on the beach
Then found more concentrated slag, iron, and furnace. All 2000 år gammal
Then wen back and looked at old collections
C14 dates work on steel!
Even earlier date from Arvidsjaur, same age as middle east early finds
Methods
High carbon steel, high quality
Roman ore high Mn. So is ours.
0,8%
As found:
Missed a photo
Need to trade off for ___ hours, keep tempo
Jarnlump
Små fragmenter ramlar. Det hittade vi.
Quality steel
Felra steg. Behändlet och förbättra
Holkyxa av stål
Knife edge harder
Temperature blended ovanligt, but we did it
Clearly knew what they were doing
Multiple metals in one slag:
Lodning Plätering Decorative
Needs control, small temperature windows
We only have slage evidence, here, so far
Bronze plated spear
Many stages
Collect
Climate matters, some of this is seasonal
Summer:
Dry trees 1 2 seasons before coal
Take lera to place in winter?
Small communites
Probably collective work
Water also had fish
Ore 1.5 to 4 m djup can be very near shore
Chewed bits of dried fish found
Used to think settled in winter and nomad in summer
But iron smelting needs more in place in summer
Well developed technique, no trace of experimental stage
Already advanced 300 BC. How so quick spread? That is current focus of research
Went back to this photo
- find the better version and fix record
So much iron needed per farm, so we produced enough in one place for ___ farms
Requires a system to keep the knowledge and pass it to next generation
There is trace of bronze work in north but no one has researched the other metals, yet
Phosphorus iron also found here
80 kg malm i Sangis
There are likely more production places unfound Asbestos ceramic, from that period. If it is there, analysera the slag
