interestingly enough, this pattern pops out when etched but if you twist in light, the cementite is in the 'black' area's.

Klaas,

 

How nice it is to see a wootz post now and then. I have seen this as well..at the time I assigned it to carbon spheroidizing in the dendrite stalks..incomplete migration during the spheroidizing process. I have some old pics of a pattern as forged and after an incomplete sheroidizing ( I will look for them ). The iron contained chromium traces at that time (may or may not be related)...I have changed crucibles and should be chromium free.

 

That is a nice pattern as is ...

Jan
