This is not a negative review. I just want to help others not to make the mistake I made thinking this can be used in the same way as iron oxide black pigment. In the photo it took 3/4 cup of pigment added to the same amount of lime to get the dark color on the left. Light gray on the right after the entire 5 lb bag of Fe3O4 has been added. If you want a true black pigment, get "iron oxide based black COLOR PIGMENT" like Color Rare. It's not Fe3O4's fault that it can't be a dark pigment, it was my fault.
