Our synthetic black iron oxide is a very pure form of Black iron oxide used in many scientific experiments as well as home DIY projects. This can be used to make Magnetic Slime and Magnetic Putty.

Better than expected
I received so much more than I expected and it was so much fun making magnetic slime! Many more batches to come- there is so much powder I feel like i need to find more cool things to do with it! Very happy with the price and quantity.

Messy, messy, terrible.
This is the messiest nastiest stuff, do not let your kids order it unless you enjoy cleaning.
