... or with a muller until a homogeneous, smooth, lump-free paste is achieved. If the pigment is hard to moist, add a few drops of Ethyl Alcohol (#70805) or Ox Gall (#78087) as dispersant. Prior to application, the paint is thinned with water as required. Test the paint on a piece of paper: If it shows chalking, add more watercolor medium. If the paint feels tacky after drying, add more pigment. If the painted surface shows little granules that will smear when you rub it with your finger, you need to mix and grind the pigment more thoroughly.

Nota

Most pigments work well with the Kremer Watercolor Medium. Pigments used for watercolor should be as fine as possible, because it is usually difficult to bind larger particles, such as coarse-grained earth pigments or sand. Reactive pigments, such as copper based pigments, manganese, phosphates or cobalt, are not recommended for watercolor. The easiest pigments to mix are cadmium -, cobalt -, and ultramarine pigments, iron oxides, and earth pigments. Synthetic-organic pigments are difficult to moisten, they dry slowly, need a lot of binding medium and have to be ground thoroughly to remove larger particles that will cause lumps in the paint. Pearlescent pigments, on the other hand, should not be ground too much. They consist of tiny flakes, which can slow down drying of the paint later.
