Another wootz question

[Jeff Pringle]

I’m sure the Turkish, Persian and Indian smiths were primarily working with metal from different production centers, which used somewhat different ores and processes. But perhaps the Turks were buying up all the ingots that were less prone to material loss and fracture while forging…
To recapture the old metal requires orchestrating the alloy, the ingot, the forging method, heat treatment, and even the polishing and etching - all have significant effects on the finished appearance.
To illustrate the importance of the ingot alloy to the pattern, here is metal from two modern ingots that were forged in a similar way. One of these is not going to ever look Persian!
