Thread: Tamahagane smelt....

Hey guys, I am going to take the video's down. I want to do some work on them and repost them later.

Thanks for all the help guys,

not sure if a fccexpert is sufficient here

The raw ore is non-magnetic. Probably because the lattice structure of the iron crystals is disrupted due to ore processing. On heating, the iron lattice matrix is able to realign itself due to the changes in the iron crystal (face centered vs. body centered cubic) and becomes magnetic. Since we live inside a huge magnetic field, it'll orient in that relative direction.

I can understand the rest of the technical stuff but my lips get tired. That's the Cliff's notes version.
