It was more interesting that this smith uses a can of thin material to put something in . I think metorite chips ? You can use nickel from the outer case of nickel-cadmium-batteries for bright layers in pamor. Together with the chips it will be possible to create some bright layers starting with 5 layers as seen and fold it to the number of layers you want. Thin layers of nickel tends to move into the iron and creates an alloy. After folding into e.g. 100 layers these nickel layers will normaly unvisible due to the thickness but you will see it after etching due to the fact that the nickel will alloy the iron to a thicker layer with a higher percentage of nickel content.

Good info, I always ponder why he puts 'things' into that thin can. Thanks for sharing.
