GlobMarble Terra Cotta Iron Oxide Powder Concrete 1 lb Bag - High-Coverage Powder for Vibrant Color - Perfectly Suited for Concrete Color Pigment & Dye Applications

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.

Great quality. You only need a little. Very pigmented

It was delivered a week earlier than estimated.

Good

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!

I use this brand to color my white cement. I mix with water first then add my cement. Very concentrated and true to color. I have ordered alot of there colors. LOVE them.

When added to my encaustic wax recipe, I found a cheaper alternative to the higher priced (great quality, however limited) competition. This was perfectly milled and easy to just blend into my other waxes, if needed. All by itself (including my encaustic wax recipe) I had no issues and found a brighter, thicker white than the ready made waxes out there. Im sure this will blend nicely into acrylic mediums, as well as oils. Great price, quick shipping, and im very happy. Will buy more and look forward to trying out their other colors they have available. Well done!

The GlobMarble Concrete Pigment 677 (Dark Chocolate) did not produce any color, which is supposed to be a dark chocolate. I mixed the powder material according to their instruction and once poured, it was a nice rich chocolate color, but after about a week the color disappeared (see photo). I contacted the seller and asked for a refund and their response was "With our return policy we do not accept return/refund for used products. We do apologies that product didn't satisfy your expectation." I am not asking for an apology; I am asking for a refund because the product I received did not perform as it was supposed to. I will not buy from this company again due to this incident.

Amazing rich colour in my soaps and concrete.
