It is believed that Wootz was produced as far back as 800bCe in Southern India and Sri Lanka.
It is a hypereutectoid 'Crucible' steel: i.e. its temperature rises to the point where it melts and the organic additives included in the crucible, which was a "clay" watermelon shaped vessel, become evenly distributed, as opposed to folding and hammering. Those additives were rice husks, pomegranate peel, wood chips and leaves (?); also, it has been suggested that glass was added to homogenize impurities into a slag layer on top - but I remain uncertain as to the veracity of this suggestion. The forges were on hillsides, and tent-like funnels directed wind into the furnace to achieve the necessary temperatures. The resulting cakes of wootz could then be forged into blades given the appropriate knowledge and ability - which was not always a given. So, was this method practiced in the Middle East? That is my question. Surely this is known and established. Last edited by urbanspaceman; 13th November 2024 at 06:13 PM. Reason: typo |

The 'Crucible' method was lost until 1744 when Doncaster born clock and locksmith Benjamin Huntsman - in search of a perfect mainspring - moved to Sheffield and finally perfected the process.
Unfortunately, paranoid and guarded until the end, he never patented the method. This method is the basis for modern steel making using the Bessemer converter. There my knowledge ends. |

Beware of typing Wootz into Youtube unless you are retired.

Sweden was primarily famous for its 'Oregrounds bar iron' which was very pure.
'Newcastle' steel, traded from the late 1600s into the 1700s, was produced by William Bertram in the Derwent Valley (Ca.Shotley Bridge) and recognized as the finest steel available anywhere. He was known for using the 'German Method', which isn't surprising considering he was born and raised in Remscheid before moving to Wira Bruk, then Shotley Bridge after marrying a Swedish lass. At its finest, it was almost too hard to work, and Sheffield tool-makers, when manufacturing shears for the fabric industry - 'Shear Steel' - complained... asking for a softer product. The Bertram family descendants were producing "The World's Finest Cutlery" as late as the 1970s under the Hen and Rooster label. Naturally, William was buying his bar-iron from Sweden and supplying the German smiths in Shotley Bridge with their steel; hence my knowledge of him.

There used to be some interesting videos of Al Pendray and John Verhoeven using ore from Damascus area and crucible technique assisted by local smiths to recreate crucible steel.
Has anyone mentioned the local variances in ores effecting the final outcome of the crystalline structure? |

I remember seeing a lengthy documentary quite a few years back about Al and John making wootz: it was mesmerising; the more so because I had not yet begun my Shotley Bridge odyssey and knew nothing about arms, armour or metallurgy.
I have not yet found it on Youtube although there is a superb video featuring Al that is easy to come across if you type wootz and his name into the search engine; this will bring up an endless number of additional videos on wootz (and blade metallurgy)... as I said, take a week off work. Equally, there are many of those videos regarding steel composition - and iron too. Despite sending smiths over to the Middle East during the Christian Crusades, to steal the secrets, the Solingen blacksmiths have never used the Crucible method, which makes me suspicious about it ever being used in the Middle East, which is what prompted my question. The local ore that was used in Remscheid is significantly responsible for the blade quality output from Solingen: breakdowns of ore content by location have been published extensively. The other important factor responsible for the high grade of blade output from Solingen, and Hounslow, Shotley Bridge, Klingenthal et al. is the specialisation system, where separate guilds (usually family based) performed only one process/stage in blade production; and considering it had been going-on for 2,000 years, they had definitely mastered the arts. Forging was, of course, the "Black Art"... worldwide actually, as I'm sure everyone is aware. Last edited by urbanspaceman; 13th November 2024 at 08:42 PM. Reason: addition |

There has been much consideration over the years/decades regarding the ending of fine blade production in Damascus, with the predominant reasons considered being the loss of the blacksmith's secrets as families died out, but also the depleting of the necessary local ores.
I would be interested to learn what research has been done about this. |
