Red Iron Oxide - Fe2O3 - Natural - 5 Pounds

I've written reviews about this for other products that I've mixed it with. Using (red) rust to color concrete or to use it as stain on raw wood is one of the smartest things you can do. I've used it for years and the fact of the matter is it's... rust. It's not paint. It's not going to (ever) flake off or fade. So you never have to reapply it. And it's a wonderful neutral natural color. I buy it in bulk and then mix it with Ferrous Sulfate, (which is a great wood grayer and wood protector) that's safe to be used in planters, even with vegetables, right up against it. Or I mix it with Boiled Linseed oil and you have a wonderful stain with a natural waterproof capability. If you want a maintenance-free (for decades) product and also something that's not toxic to humans. For garden beds or other uses, use red iron oxide.

Good quality

Works great I use it in the garden for certain plants and along with electro culture. This is a godsend the past two years I've had the best crop yielded ever.

Great price for how much you get. Colors very well. I received black but ordered red. They let me keep the black & sent a red batch right away. Very impressive for sure. I appreciate that. I make mini bricks so I have a lot of red dye to make a lot of mini bricks. Buy from them!

This is basically rust; but it’s very finely powdered, which makes it a great additive for paints or adhesives that you’re using for artistic applications. Adds a nice swath or splash of red to anything you want to swath or splash up.

Great for thermite reactions!

I purchased this looking for pure Fe2O3. It is clear that this is NOT pure Fe2O3, rather it is iron ore with a large percentage of Fe2O3. It also contains a fair amount of hydroxides (evident from H2O that are released when heated to abut 600F). Useless for thermite reactions, sadly -- as it barely sustains combustion, and the iron yield is nonexistent (less than 1%). Update: Assay using boiling HCL shows that only 73.6% of this is acid soluble, setting the upper bound for iron oxide content. If you still want to use this for thermite, which I do not recommend, you will want to adjust your weight accordingly.

That's one big bag of rust you get for your money! As for a rating on "Thickness" and "Sheerness" that the review form requested, I know not what to suggest. I didn't know rust could be sheer. But, okay, I'll bite. This rust is very thick and sheer. More importantly you get a lot of it for your money and, saves you the trouble of scraping It off your kids old swing set or the underside of your SUV.

Great for making custom inductors. You can also use it for its intended purpose of being a pigment.

Good Product, good delivery

I didn't realize this thing is heavy

Color not what I was expecting but not too far off

Great value
