Dendritic Steel in Metallurgy and other enigmas Posted February 12, 2008 · Edited February 12, 2008 by Arik Estus I get this all the time with real old 1075. Yes I mean really really old stock. Tinker asked me if it was wootz. He seemed surprised when I told him what it was. The patterning is never the same. Sometimes more pronounced then others. I like it and so do my clients. OK, I re-read the patent for the "wootzy looking steel". It sounds like he is equateing quenching to cryo. So now any fast thermal conversion is an infringment? Isnt quenching in oil or water a fast thermal conversion? Ive been out in my barn to long. All this legal stuff just makes me want to call my lawyer names.
