Bulk Iron Filings- 1 LB Iron Filings for Science Experiments, by American Heritage Industries

It worked surprisingly well as a tool to strip copper out of a solution. I was able to eventually cement out copper on the powder with remarkable speed but had to keep the solution moving with a magnetic stirrer, lest the cementing copper turn the iron powder into a glob. It was difficult to work with only because I had wanted something I could pour my solution onto and forget while the copper cemented out. But that just means either I'm lazy, or it wasn't ideal for the task I wanted. I can't complain about the price or the quality. If you need powdered iron - this'll definitely do.

Used this for magnetic slime. Worked great.

I bought this for my son to try different experiments. It’s cool to use different magnets to see how it reacts!

I’m making some resin art pieces and want to make them magnetic so fingers crossed!

I weighed the product, including the plastic bag, and it weighed .97 lb. Not a big deal, but if you were going to be a bit more generous, say, 1.01 lb. would that really impinge on your profits?

Used this for my daughters science project and it was great and fun

These are not actually filings. They are better! They are very small steroid shapes which are very consistent in size. They are very clean and not dusty. Excellent quality and nicely packed.

My 9 yr old nephew is totally into science projects
