Pur Filters

Hey, I’m making iron oxide for an experiment with plant fertilizer and stuff. I am making it through electrolysis. I tried to ways to get the iron oxide after wards. I tried to boil out all the water, and filter it and then leave it under a lamp to dry it out.
When I filtered it and dried under lamp it was brownish like normal rust. When I boiled out the water it was kinda black.
Is it still rust? I find boiling out water if faster but I was wondeirng if its the same stuff.

Thanks!

Rust is hydrated iron oxide. If you heat it you can remove the H2O and the appearance will change.

Why I don’t understand is why you are making it this way. There is plenty around naturally.. most people can find it in their garden shed. Or why not just leave damp iron filings .. they rust within a day?
