Good to see you back here and great work.

I'm really fascinated to see other metals like Chromium, Molybdenum and Cobalt. Somewhere I saw the purity of the metal can benefit if you add a flux to the mixture as well as form the bottom of the cup with a high melting point refractory powder to help pool the metal.

Would love to try this out myself, but 1) too many other priorities 2) you can quickly get into trouble with the police here playing with thermite!
