If I remember correctly from geology and chemistry, Fe3O4 is magnetite, and doesn't form as rust. Where are you getting such quantities of magnetite? And why are you using it for thermite reactions? Surely it's more fun as a magnet.Originally Posted by JimBob
I like Australia's school system GPM, it works. Even the much lambasted public schools (and I went to one of the badder ones in Perth) do a good job for the students who want to learn.
