How long did it take you to make this video? This seems like a hard project to complete.

2024-07-07 19:31:02 +0000 UTCThey must have some method of doing that for rail welding since slag in the weld would be a safety hazard. In the video I watched the pour was a little delayed after they started the reaction, so I'm assuming they had a metal disk or something that melted out of the way once it reached a certain temperature. That would give it time for the iron to settle out

And I couldn't help thinking about that time you helped out the guys with their ancient furnace, and I thought "modern day Neanderthal Cody, getting the iron from inside his furnace" π. Also love how at the start, you have a perfectly functional furnace there, to preheat the crucible, definition of overkill. (Though I think Maxwell has the right idea, and you should skip the crucible step when you do this again)

2024-07-05 00:55:27 +0000 UTCI think that wetting the sand underneath your pour spout and basin may allow for the sand to hold its integrity longer. You could maybe use a drip line under the sand or something to allow for it to hold up during the intense heat. Also, if you mess with the the composition like adding copper it may make it more ductile.

2024-07-04 23:12:54 +0000 UTCI don't think so. The iron and aluminum do something on cooling that make the metal crystals not go together right or something. IIRC (I saw it on the history channel so who knows if it's accurate) the Roswell crash had some feroaluminum foil which was bendable even though that alloy should be crumbly. So maybe ET figured it out. Lol

2024-07-04 14:57:04 +0000 UTCcan you temper the pan to make it less brittle?

2024-07-04 14:49:14 +0000 UTCVery cool! If you haven't already, you could look at how they do thermite rail welding. I think they add additional iron and to the mix which would mean more iron per reaction and it has alloying metals in it and could help with the quality of iron you get out. They also have it set up so that the iron flows directly from the reaction into the mold, which would eliminate the crucible issues you were having and would mean the iron goes in hotter and might not create folds
