I have had a few rusty nails, and I tried to scrape them off to make IRon oxide, for a projectBut I tried to scrape with a knife and crumpeled aluminum foil, nothingJust little very tiny bits, which disapear into the surface of the bagWhat am I doing wrong? Or, if you don't know what is another way to make Iron Oxide (rust)? Please Help?!
My mom always did that and we never had any problems.The heating element is above this so ventilation is not the issue
you first get iron you pour salt water on it (speeds up process) and you waitIt's simple!
