BULK IRON FILINGS- This 1 LB jar of pure iron filings are perfect for scientific experiments and educating the young learner.
PURE IRON FILINGS- These iron filings are pure iron.
This makes them ferromagnetic and a great item to use for testing with magnetism.
These are iron filings, not iron powder, which makes them more manageable and easier to navigate in the classroom.
METALLURGICAL GRADE- These iron filings are pure and metallurgical grade.
This means you’re getting pure iron, free from other chemicals or additives that can damage the results of a scientific experiment, or introduce unwanted chemicals into your home or classroom.
MAGNETISM EXPERIMENTS- Because of its ferromagnetic properties, iron filings have been a staple of physics and science classrooms nationally for decades.
It is a great way to physically demonstrate the way that magnetic poles and magnetism work.
QUALITY GUARANTEED- This product comes with the American Heritage Industries Guarantee.
If you have any problems at all with your pure iron filings, reach out to our Midwest based customer service team and they can help you, or walk you through potential uses.
If you are not satisfied in anyway, we offer a money back guarantee on all our products!.

Most companies who claim 99% EMF reduction refer to their EMF blocking fabric, not the EMF reduction you receive. Some companies even sell stickers and pendants with a tiny piece of EMF blocking material and claim 99% reduction, but the real reduction to you is zero or sometimes worse, especially if applied to the back of your phone. ‘EGCLJ’ only sells products that provide real protection and is based on scientific principles..
