Grinding the pigment with water on a stone slate can be quite exhausting and can take more than two hours for certain pigments like those derived from peach pits. This first grinding step has two goals. First, the pigment is ground into particles of the correct size, and, second, the particle morphology is homogenized to create uniform particles.

Once large agglomerates are broken, grinding becomes inefficient. The lower limit for ball-milling TiOg pigments is about 7 Ju,m. Media and sand mills accelerate balls by means other than gravity. In these devices millimeter-sized grinding media cascade over pigment agglom- erates, grinding them into individual crystals by attrition.
