Review on Lab & Scientific Products: Natural Black Iron Oxide Pounds by Mark Jefferson

Revainrating 1 out of 5

Teachers and Magnets!

I am disappointed that this is a fine powder. I wanted to use it with magnets and kids and they look like miners. Are you trying to find a practical way to share this with kids for science?

Pros
  • Fe3O4, also known as magnetite or ferrous oxide
Cons
  • Crumpled packaging
