Pigment Grind: How to Efficiently Adjust the Fineness
In the industry, the fineness of grind is generally achieved with a 2-step process. First, developers and producers of paints use a dissolver to reduce the particle size of their pigments and fillers to a certain degree of fineness. Then, when needed, they additionally use a pearl mill to further separate the solid particles from each other.

How to disperse and stabilize pigments
The solid/gaseous interface ( pigment/air) is transformed into a solid/liquid interface (pigment/resin solution). Grinding stage: Through mechanical energy (impact and shear forces), the pigment agglomerates are broken up and disrupted into smaller units and dispersed (uniformly distributed).
Hand Grinding and the Purchase of Materials
First, some dry pigment must be put in the center of the grinding slab with the addition of the binder. If the pigment does not accept the bind, it may be wetted with a small quantity of water. The two base components must be mixed with a spatula until a very stiff paste is obtained.
