Thermite questions

I made some Iron oxide from using a car batterie charger and some salty water and i made some aluminium powder from putting aluminium foil in the blender for a while, I mixed it together and i used my blowtorch to ignite it but nothing happened can someone tell me why

if you want a first time go, then you need to pull out the big guns and use a sparkler, not the cheap sparklers but the big ones.

You've got to get the proportions right (if I recall correctly, it's about 7 parts aluminium powder to one part iron oxide by weight).

The correct mixture is also quite hard to light. If you can get magnesium ribbon, that makes a decent fuse, light the tip with your blow torch, but do not look at the magnesium flame - it gives out enough UV to damage your eyes.

1. You'll put an eye out.
2. Use the top search box and put in "thermite".
