Terra Cotta Iron Oxide Powder Concrete 1 lb Bag - High-Coverage Concrete Dye Powder for Vibrant Color - Perfectly Suited for Concrete Color Pigment & Dye Applications - Easy Mix, Long-Lasting Concrete Color

I couldn't really get a true black out of this pigment or close to black. The best I was able to achieve was a charcoal color, which isn't a big problem because charcoal is one of the more popular colors in the items that I sell. Still a good product at a good price, but definitely not black, even when you oversaturate your mixture with pigment. It definitely helps tone down the yellow hue of CementAll, even if you use this pigment to achieve a gray shade.I'm going to try the Supra Black next time and hopefully it will get me a shade closer to black, which I need for some of my trays.

This is the best black concrete pigment ever! All of the others just turn cement a dark gray but this is the truest black

A little goes a long way. I added it to a small tub of concrete patch to repair my terra cotta sidewalk. If youre trying to match what you already have be sure to wet existing cement to get the proper color match..as it lightens when dry.

I feel like this is a very generous amount for the price. Have bought with other sellers and I feel like they take advantage. Package will come with a little bit of lose powder but that’s normal since it comes in a tiny concrete looking bag.If you’ve ever bought concrete then you’ll know that lose powder is normal. Haven’t tried the product yet but I’ll keep y’all posted!

I’m just in LOVE with this Supra black pigment!! It’s the best, truest black I’ve seen on the concrete pigment market! But be careful because it is very messy and you have to do a lot of cleaning up but it is totally worth it to create a pure black product.The other ‘black’ pigments I’ve used are really just a charcoal color and never quite reaches that deep pure black color. So glad I found Globmarble! I’ll definitely check out their other pigments!

This is a great way to add a nice bright white to a stepping stone, easy to add and stir into the cement mix. Really makes your add-ons (such as stones or beads) stand out.

This is the only pigment that i was able to tint diamond veneer plaster with true lamp black without affecting the strength and consistency (I’ve tried a hunch of universal colorants - they don’t work for diamond veneer) . Oxides work but they have ugly brown undertone. This is true charcoal deep black - as good as it gets.

Give the color but will bleed black on everything
