Making a Sword with THERMITE!

  • Published on Oct 11, 2017
  • Usually Thermite is used to destroy things... Instead, I wanted to use it to make something to destroy things with.
    If you have never heard of it -Thermite is a mixture of Iron Oxide (rust) and Aluminum powder. When you ignite it a vigorous chemical reaction takes place which results in liquid iron. Its used industrially for welding metal, the military uses it to destroy enemy equipment, teachers use it for science demonstrations, and youtubers just melt stuff with it.
    I made a mold out of insulating firebricks, and set off the thermite over it to fill it with molten steel!

    Oh boy....just thought i'd let you know that water and molten metal in combination, is about as bad an idea as ideas are in risk of very very serious injuries, if the water turns into a steamexplosion, and sends molten metal in every possible direction...even very few drops of water can create a very unpleasant scenario for you.
    Just saying....

    Do not heat treat with water it extremely difficult to master without causing major cracks and weaknesses in the blade, even the world best swords smiths use an oil clench. With the exception of Katanas which are notoriously weak swords.

    Should have oil clinch the sword instead of water to have less cracks in the sword and you should use a angle grinder on the blade a little and on the flat sides to give it a more authentic look
