First of all, always be careful when handling. This absolutely should not be inhaled or allowed to get in your eyes.I used it to make a purple stream out of acrylic and it's great. A little goes a long way and the color is amazing. It's not transparent at all. That was great for me, because I needed it to be solid. I've only used it once, but I so far I love it.

I'm glad I read the other reviews before I dove into a project with this. But before I'd done so, I opened up the first bag and encountered a little bit of a dusty puff of a chemical odor--not too strong, but enough to make me put off what I was doing and try to find some directions.I got Red Oxide.I turned off the fans, closed the window, put on a face mask and gloves, and laid down some newspaper. Then, I opened up that second bag, and added a 1/2 teaspoon of the powder to about a 1/4 cup of matte Mod Podge to paint some raw wood shadow boxes.A little does indeed go a long way. They dried perfectly. I put on a second coat, just to be on the safe side, but my project looks really nice.If this pigment came with instructions on how to prevent eye and lung injury, it would be a five-star product. But aside from that, the results are excellent.

I did not know what red iron oxide pigment powder was so I looked it up. "Red oxide pigment powder is primarily made of iron oxide compounds, specifically ferric oxide (Fe2O3)." It had a couple images of it and it was dark red. So I looked up how can red oxide pigment powder be made brighter. It said that the compounds had "various grades designated by numbers, typically ranging from 120 (lighter) to 180 (darker)".One other thing I was concerned about was if it were toxic, and it is not. But in the powered form it does caution the use of it. One must wear a respiratory mask and gloves while handling it.It should not be inhaled either. I did not know that when I opened the package. The main package is a plastic bag much like the ones used for beads and other craft items. This bag was in a mylar bag. When I opened the mylar bag I could smell the fragrance. Fortunately I was not inhaling the power as it was in the closed bag. However, I could feel some sort of residue on my hands that left the fragrance on my hands. The research I did (after I handled the bag) also cautioned to wash hands that handled the power. Since I did not know, and still do not know, what was the stuff that was getting on my hands, I washed my hands and I now know to use gloves from now on. I think I will be pouring the pigment in a jar to keep from handling the bag with the residue.The research I used also mentioned all the properties: its "excellent tinting strength, high color purity and stability, resistant to fading or bleeding, good light fastness, heat stability, and weather resistance." and more. This makes for a good quality pigment for use in resin, candle wax, cement, and many more compounds. So I highly recommend this red oxide pigment powder.

100/100I can't speak to every use, but THIS is a beautiful, deep ultramarine blue pigment powder. It arrives in a plastic bag inside another heavier bag. I immediately "decanted" it into a glass jar that has a good, tight seal. It is a fine powder and seems to be pretty clump-free.Ultramarine is the color that was originally derived from Lapis Lazuli and in times past was VERY expensive. Lapis is my "thing" soI have a lot of Lapis stone and this pigment is perfect for adding Ultramarine to practically any project.Ultimately, is it worth the price? Yes

I love the rich, red color of the resin when I've mixed this pigment powder into it. The pictures above are some experiments I performed with this colorant. With the fist mold, I wanted to see if I could add a different color base after the main mold was already cured, and the red seemed like the perfect color to offset the green. It worked beautifully and I love how nice the red looks as the base of what is now a small flower pot. The next picture is of an outdoor scene. There, I swirled red with gold, and the color is much more striking than the picture shows. It took a very small amount of this powder to get the brilliant color I achieved, and since it comes with 5 ounces, it'll last through many projects.

it is definitely a solid color no matter the amount you use it is not transparent keep that in mind if you need transparent look elsewhere, this does come pretty close to the advertised color and i find that somewhat difficult buying on here you can't know for sure until you see for yourself. now i did find that if you use to much of this it will go from nice green grass to slightly bluish AstroTurf , so practice before you go all in.

I love this bold red pigment powder! I use it with epoxy resin, but it would work great in concrete or for other applications as well. The color is very bold and gorgeous, and holds it color well when mixed and after curing. I highly recommend this gorgeous red pigment powder to others. I do wish it came in a container though, instead of in a plastic bag.

I got this because I needed a really intense red for my epoxy resin projects, but I was disappointed to find that the powder does not mix well with 1:1 shallow pour epoxy. The powder clumped up rather than spread through the resin, and the overall consistency of the resin was affected. There must be some kind of chemical reaction triggered between the two, because the resin did not at all behave like it usually does. So if you're looking for a red for your resin, stick to alcohol inks and mica powder.
