    I've posted photos of the iron prills that I melted together in a crucible to form a single ingot (it's in my community tab here: .This was done using the forge blower blasting air down onto the crucible covered with charcoal in a small furnace. It is indeed iron metal as it sticks strongly to a magnet and has a shiny metallic luster. I believe it to be cast iron as it is quite brittle, though in other experiments I've made malleable iron from the same iron bacteria which could be flattened when hammered cold. Thanks.

    Пускай к нам приезжает на средний Урал, я посмотрел бы как он в труселях бегает. Сейчас 29.07.19 а на улице +15 градусов. И это летом про осень с зимой я вообще молчу.

    Quite surprising the amount of effort required to produce not even 1kg amount of iron/ bronze, granted our ancestors lived in larger groups but it's still a wonder how people the world over realized that their was something interesting about these tiny pellets, especially given the lack of even a written language.

    That’s a nice bit of slag you got there…but it looks so lame and lumpy.

    Tired of using lame, sad, metal? Use bronze. It’s copper with special ingredient tin, from the far out regions of tin-land. I don’t actually know where, my dealer won’t tell me where he gets it.
