Thanks again Mr. Obach for the time and information. To answer your question on the hurdle. I guess the biggest hurdle for me is the thousands of questions that wait at every step of a new adventure, ie . equipment design and size, materials to use and not to use, temps, times, weights of raw materials. The tutorial and the paper that you wrote has gone a long way to answering most of the questions. I'm trying to decide on a furnace now, looking at Mr. Gingery's.
P.S. If you ever decide to write a book on wootz, in the spirt of the complete bladesmith, I'd like to buy the first copy.
