I know that this stuff is some nasty shit. A friend told me that it will turn sand into molten glass. I read some instructions online as to how to do this and they went through the whole thing of making rust and such.

After I made the rust... and let it settle in the jar, it turned black and not red.. as it should. I then cooked it in an old pot (as instructed) to try to make it turn color... it didnt. I ended up with some black powder... and im scared as shit to burn it because its not as described in the documentation.
I'm wondering if the pot has to be iron to cook it (The instructions say iron, but not otherwise).

Thanks.
