First wootz!

Remember that wootz ingot I was hoping was actually wootz and not just a waste of time, propane, and enthusiasm? I finally got it sectioned, polished, and etched. There's dendrites, carbide needles large enough to be seen by eye and over a cm in length, clustered in groups and intersecting each other. The slag inclusions are only at the very top, and will be easily removed (they shouldn't exist at all, but I'm not complaining). I'm going to keep this small section for bragging rights, and see about turning the other largish chunk (almost 750g, enough for a small sword) into something.

This was produced using the experimental thermite process I've been working on.

For reference, this piece, as photographed, is about 9.3 cm wide. It was polished to 320 grit (A45 Trizact) and etched with ferric chloride. Those lines in the ingot that look like scratches are actually dendrites, all grinding scratches are along the long axis and are pretty much invisible in this picture.

Ack, it's already rusting, off to apply some oil.
