This makes me wonder what kinds of things that we normally do today will be unknown in the future, maybe handwriting since everything is becoming digital 🤔
I come from the Trøndelag region, where a lot of the original Islandic pioneers came from. The production of bog iron was a small industry there, even before the Viking age. The Roman Empire got a lot of their iron from bog iron like that. And in Budalen, in Trøndelag, they say that the nails used to crucifix Jesus was made with iron fromt their bogs. This is a video that shows the prosess from start to end. ruclips.net/video/80omf7bM3Ek/видео.htmlsi=xe8ntZsAgxdNgMuv
How can clay not be able to handle those temperatures? All clay is made up of silicates and should handle a high temperature without melting right? Some might h be prone to cracking due to impurities, but the clay itself shouldn't melt or anything...
Clay, depending on some variables, mostly impurities, has different melting points, some clay melts at lower tempratures than Iron, other clay will survive or turn into glass through the process.
There are probably slight variations, but clay will generally start melting above 1200°C. Iron bloom type furnaces reach around 1450°C. It's necessary to add hay and/or sand to clay to reinforce the structure and prevent cracking. Furnace wall should be at least 10 cm thick around tuyeres (air inflow pipe) or you risk burning it through. In any case, clay will start to melt, drip and partially or fully clog the tuyeres. I'm not sure whether Iceland has a true clay at all. It's formation requires a lot of precipitation (ideally rainy tropical climate) and time. The other thing is charcoal. I don't recall Iceland as particularly woody. Turf might be one source, but very ashy I suppose.
the lump of iron was ruined as soon the blacksmith quenched it in the small creek ! this iron can never ever be forged to a tool with a hard Blade feature .
I find this very interesting and would love to see more of Icelandic history presented in this manner!
I found a good video source the other day so you can expect to see lots of new stuff in the coming weeks Janice :)
Just Icelandic 🙏 Thanks!
Oh you know, just James Austin there demonstrating! No biggie!! Guy's a blacksmith legend to those who care about axe forging!
Welcome
love the Icelandic history. look forward to more of these videos.
More to come!

Good point about the handwriting but it's sad Tham many kids nowadays can't even read properly, the LCD screen addiction will have it's price for sure
Ik this is a little late but my class was the last to learn anything about cursive writing so I think it’s already happening..
Did you roast the ore?? From limonite to hematite? before "melting" - shafting ..
excellent

3:57 you lost me at (using electric fan ), back to square zero, we still don’t know how they melted it seems the right answer.
