This probably is a side bar, but how much impact would the percentages of the ore or raw material(coke, coal, etc.) have on the final product? Moreover, say if the inland sourced ore had close to the desired percentage of silicon, would this lead to a quality product and hold an edge over another gunmaking centre that had to modify their own mixture. In Belgium, take the Societe Perard & Mineur for example, were the craftsmen getting their iron & steel from one source for the pattern welded composition?

Kind Regards,
