I normally wouldn’t leave a review for something like this. It is what it is. BUT, I wanted to comment on the excellent packaging. I’ve ordered this from other sites and there’s always a bit of a mess in the box. But this was as clean as clean can be. It’s even in a white bag and there’s absolutely nothing on the outside. Really great.

This seems to be some rather high quality stuff. Wear a dust mask when using because it's very fine powder.We bought it for making magnetic PVA glue slime, but it of course has a variety of purposes including black pigment.

I mixed the entire 5 lb bag into 1 gallon of paint applied in 4 coats - testing between coats - the fourth coat did the trick. This covered a 4 x 8 ft plywood sheet. I like the option of picking my own paint color rather than the chalkboard or magnetic paints advertised. Remember that the black powder will darken and flatten any paint. Recommend mixing in smaller batches for each coat and using a drill stirring stick rather than mixing by hand.
Happy Mario !

Fantastic price. We used it to make magnetic slime to go with some rare earth magnets.

This superfine powder is perfect for making magnetic slime. It's a great value in the 5 lb. bag if you plan on making a lot of it. Do not confuse this with iron filings, which some online slime recipes use - this is a fine black iron oxide powder that will make slime that is magnetically reactive. I'm sure it has many other uses, but my last chemistry class was in high school.

It did not work for magnetic slime, but may be useful for other purposes.
