Marius, Iím not sure I understood your PS correctly

In the 19th century, there were undoubtedly blacksmiths in Persia who made swords from wootz. They exactly produce wootz in the 19th century. There is an article of 1842, which was written by a Russian officer who was in Persia and himself observed this process.
Unfortunately, the article is written in Russian. But I can post it here if it's interesting, by attaching scanned pages.
