  • what are they salt cubes?

  • @Mike20151 its made of refractory brick, similar to the kind found in kilns for firing ceramics. unfortunately, this furnace was destroyed after its first run because the inside of it had melted all the way to the outer wall

  • melting tungsten? damn thats gotta be sooo hot

  • @starshock01 you should take a look at my new furnace. its on MrExTech, my other channel. instead of this one's 1000 watts, the new one is 10kW. the video is titled "carbon arc furnace"

  • can you use an arc welder with carbon rods for this

  • yes, in fact it works very well

  • I beleive that at close range, if you put a magnetron from a microwave (still connected to the transformer obviously), right next to the crucibal, you will acheive the same results, though your tempurature will be limited to about 1500-1800, which is hot enough to cast aluminium, zinc, gold, lead and other goodies. its the basis of how instant gold microwaveable furnaces operate.

  • What Powersource Do You Use??

  • Dude!  Cool video, but I hope that paint can is empty! LOL!

    I learned something like that watching videos similar to this! Be careful... Hope I see more from ya! Just not the wrong kind! LOL

  • hi, thx 4 ur vid but how did u set up the electrical system of the heating element?

    thx alot

  • where did you did you get the carbon

  • @redneckghettotech these ceramics must be well pressed inorder to last more and more

  • That is most excellent. I would like to build an Electric Arc Furnace for the Production of Calcium Carbide (from CaO and C)... but I dont quite know where to start!

  • thanks for replay *_^
