This is very interesting technical information Timo, it is something that for the most part I do not know, in fact something I have not needed to know, my knowledge in this area deals with forge work, and I --- and I believe most other people involved with forge work --- tend to look at all the processes that produce the material with which we work, as "smelting". Obviously technically incorrect.
I had intended to stop posting to this thread, but your posts gave it a new life, well, at least for me they did.
However we've still got King Tut's dagger sitting in front of us, and if we can now accept that it is indeed meteoritic material, which it must be if the nickel content is as high as it is reported to be, then we really only have one question:-
prior to 1323BC who had the technology that could forge weld iron or could cast iron?
welding depends on heat and pressure, but in the absence of a massive power hammer, the heat needed to weld iron is around 2500F - 2600F
nickel will weld at a slightly lower temperature than iron
casting depends upon having liquid metal, iron will melt at about 2800F
Prior to 1323BC, when King Tutankhamen died, what people, anywhere in the world, had the technology that would provide temperatures in excess of 2500F?
If that question can be answered we will know where the King Tut dagger came from, if it cannot be answered all we can do is to speculate.
--- or maybe Erik von Daniken had the answer after all????
