Meteorite Dagger?

[A. G. Maisey]

The most common method of making pamor with nickel is to take a paper thin piece of nickel, sandwich it between two layers of iron and forge weld it. You take four of these little billets and weld them together, then you forge out and double over and weld until you have 128 nominal layers of nickel.
In the finished pamor the nickel layers are quite distinct. The nickel does not melt into the iron, it stays as distinct layers of material. Probably the easiest way to think of the mix of nickel and iron, is that the iron acts as "glue" to hold the layers of nickel together.Accordingly, if you can find a relatively wide band of nickel, you have a pretty large area that could be tested.

I`m sorry, I cannot expand further on Prof Jerzy Piaskowski's work. It is highly technical, and his two largest papers have not yet been published. I am only aware of the content because I have worked with him advising on strictly keris and cultural matters, since about 1988.
