Oxides and Ultramarines
Oxides and Ultramarines tend to have rich, earthy hues. They can be blended to achieve complex, muted colors. These pigments are oil dispersible/ They do not dissolve. Experimentation is the key to successfully using Oxides and Ultramarines.
To incorporate them into your finished product, first mix them with an oil to prevent clumps of pigment. Add the resulting evenly colored oil to your batch and mix well. Oxides and Ultramarines will settle to the bottom of your product if you use too much or if your product is very thin in consistency.
