Thermite Creates a Sword

Thermite can cut cars in half but [TheBackyardScientist] relies on its ability to create rather than destroy. In fact, thermite was the key component when he casts a solid metal sword. The casting doesn’t require a furnace since the heat is produced by the thermite itself.

In case it wasn’t abundantly clear: this procedure is not without risk.

[TheBackyardScientist] compares two types of iron oxide, red and black, then judges their usability based on the post-ignition mass. His goal is to get the most metal from a single reaction. He also adds some stainless steel beads to improve the quality of the casting and to utilize some of the excess heat.

With encouragement from his neighbors and a couple of trials with fire bricks, buckets, and sand, [TheBackyardScientist] is successful. The resulting sword is treated, given a handle, sharpened, then scientifically tested with a variety of things found in a regular kitchen.

If you look in the background of [TheBackyardScientist]’s workshop, you may notice his molten PEWter gun. This steel sword is an upgrade from his recycled pewter sword a few years ago.

Thank you, [Keith Olson] for another great tip.
