Another wootz question

With tens of thousands of wootz ingots coming from India on an yearly basis, the smith needed just to verify that a particular ingot was indeed " wootzy", did not have a lot of slag trapped inside and ... that's it. From there on, the ultimate result depended strictly on the master's skills.
This, likely, explains why the contemporary masters have such hard time to reproduce the beauty of old Indian and Persian blades. Contemporary metallurgy knows precisely the nature of wootz, the percentage of carbon and the microelements facilitating formation of dendrites, the temperature/time optimization of the process etc. This is purely science, and we are very good at it.
What is missing, is the hands-on collection of idiosyncratic manipulations peculiar to old artists: how hard to pound, at what metal color, when to turn, when to grind and how much , how to cool etc, etc, etc.

Here is an example of a bulat (wootz) dagger by Anosov

He got the secret.

I don't think this is true. The Ingot was also critical. Kindi even stated it;
'Swords made in Yemeni workshops from Yemeni crucible steel were regarded as the highest quality swords, whereas those made by Yemeni swordsmiths using imported crucible steel were classified only as medium quality. This classification was absolute; the best Yemeni sword-smith could only achieve a medium quality blade even if the best quality imported Indian crucible steel was used.' Pg 59, Hoyland and Gilmore
