When in India "died" wootz?

This is totally amazing guys! I really had no idea of these dynamics in this processing of steel, and your explanations really bring new dimensions to matters at hand here with production of steel and wootz.

The focus on dendritic structure and how it was key to the production of the wootz, as well as the basic crucible method pursued by the Europeans and long extant in India where they sought its methods say a lot about the circumstances which brought about the very subtle disappearance of the beautiful wootz.

Ariel brings in a most interesting aspect to be factored in, the basic life span of those key to the apparently very delicate methods of production , which seem very much to apply to temperature controls. It seems logical that these relatively short generations of artisans with diminishing demand for the watered steel might play into lack of perpetuation of the necessary skills needed.

On one hand here it sounds like there was a secondary stage in processing the steel from ingot into wootz, while on the other, it was more to the original process which carried into the wootz stage through the control of the temperatures and cooling.

Obviously still not fully understanding , can you guys clarify further?

Meanwhile, I think that the circumstances involving these processes in the mid to latter 19th century might give us better perspective on how this most subtle and thus 'mysterious' disappearance of such an ancient art might have happened virtually 'during broad daylight' of the steel industry itself in this 19th century period.

Here is some other information and a theory of why wootz disappeared.

Although the article is fascinating, the section near the end and the conclusion is not as technical.

Note: I met the author and talked with him at a show here in Louisville, KY, USA and was able to look at and handle one of his recreated wootz blades.

The structure is primarily due to the cooling rate of the crucible at the time of production. Nothing to do with forging method of the tool or blade. .................................................. .
Not all crucible steel ended with the crystalline pattern as there was a relatively high failure rate due to poor temperature control.

Emanual, my understanding is that crucible steel, if properly forged, could show a watered pattern, and the fact that not all crucible steel showed a watered pattern was due to the forging process not being done properly. You can not seperate the two things, just because the steel had the ability to show a watered pattern did not mean every item made from the crucible steel would show a watered pattern, it had to be forged in the right manner or the pattern would not show. The poor temperature control that kept the crucible steel item being forged from showing a watered pattern came during the forging process.

I other words, if just any blacksmith pounded out a blade from a hunk of crucible steel the blade would not show a watered pattern, it took someone with the exact knowledge to forge a blade that showed a watered pattern.

Here is an example that shows the complexity of reproducing the watered pattern using modern steel meant to replicate crucible steel.
