    Thermite is Dangerous! I am really lucky that nothing worse happened and i am posting this video to hopefully help stop anyone from making the same mistake! enjoy!

    The question is now how did it create thermite I'm new to smelting and I'm smelting aluminum what caused it to create thermite???
     

  3. The rust in the inside of the steel tube contains iron oxide that reacts with the alm to make iron thermite
    I think...

    Failures suck man. I just had a good one. I was making a stacked leather handle for I new knife I have been working on. I epoxy resin I used never set and all of the leather is trashed. And I used the the same batch of resin on a peace of micarta, also trashed. But I had a new idea for I handle that I want to try. So its all good. And you SS turned out excellent. We live and we learn.

    Geeze that is scary taow I'm glad your ok. So should I sand down any pipes before I hear them.

    And damn beaver that sucks I like your knives man they're really good
     
  6. Yep I didnt really know what to do when it all happened and it sucked that all of my stuff wes brocken
    Also that sucks about the epoxy
    I like to use fibreglass resin because as long as u add even just a couple of drops of hardener it will set eventually , just takes time

    You have in spired me to melt things taow and I'm going melt me an aluminum ss soon
     
  8. cool!
    but remember to stay safe!

    I like how your parents won´t let you trade but do that kind of stuff around your house :D

    But you learn from mistakes, i think we have to expect a lot of awesome stuff from you in the future ;)
     
  11. Thanks!!!
    Yep that is one thing that I am starting to question!

    Isn't thermite iron oxide .... Try titanium it cost a lot but I won't melt from thermite because it's melting point is hire than thermites "reaction" point :p

    The thermite reaction is iron oxide reacting with aluminium to aluminium oxide and iron, giving of a whole lot of thermal energy.
    Also the fire extinguisher would not have worked on the reaction itself.
    Also, titanium will melt, as its melting temp is about 1600°C.
    Stay safe.

    Wow, that's pretty scary!

    I was glad to hear you mention this could have been prevented with the use of a magnet to check your aluminum for any steel. Sometimes things like motorcycle engine engine parts have steel pins and threaded inserts that need to be removed first.

    Your craftsmanship is exemplary!

    It´s bad when something went wrong but I don´t think it was a thermite reaction. A thermite reaction needs a mixture of 1 part aluminum and approx. 3 parts of rust. I don´t believe that your meltingpot contains so much rust. It was a simple but also dangerous aluminum fire. It´s a known problem in casting aluminum.
