Ultramarine Blue: "Lapis", deep, bright & wonderfully blue, this is a beautiful color. A 'must have' to mix with Violet (makes that perfect purple) or to use alone. While this is a non-bleeding colorant, if you add too much to your soap it can migrate into other colors in the soap design or stain washcloths. We recommend starting out at 1/16th to 1/8th teaspoon per pound for melt & pour soaps. For cold process, add 1 teaspoon of oxide to 1 tablespoon of a carrier oil like Sweet Almond or Olive Oil and mix well using a mini mixer. For more information on oxides in soap, check out this blog post.
To create the color in the sample of cold process soap above, we used ½ teaspoon of colorant (about 0.15 oz before dispersing) in 1 pound of soap.
