This is my absolute favorite black to use. I've used other black oxides before and they're not comparable. I go through this like crazy because I also use it to deepen colors as well. Just don't use to much to do that or else it'll overpower it.
Even though i forgot to mix it with some of my oils before i used it it dispersed really well an didnt speckle any
Used for CO soaps. Makes a great color darkener if used right and the black is exactly what I was looking for.
Black iron oxide
Love it , makes a wonderful black cold process soap.
Works really well in cold process and I also use it in melt and pour for embeds.
