Ultramarine pigments exhibit excellent resistance to most chemicals and solvents, but are attacked by acids which split off hydrogen sulphide and cause fading. Special grades of ultramarines with distinctly improved acid resistance are available. Ultramarine pigments are easy to disperse and safe to use in toy and food contact applications.
Oil Absorption and Grinding Cobalt blue absorbs a moderately high amount of oil; about 55 grams of linseed oil per 100 grams of pigment to make a paste. It has been noted in some manuals that the pigment works better as a watercolor than it does in oil, and is highly valued on that account among moist colors used by artists.

Saturation Level of the Paper. The general rule is that the drier the paper, the less effect the salt will have. Placing salt on a very wet wash or pigment load will result in a lot of movement, while sprinkling salt on a nearly dry wash will result in a very limited effect.
The ultrafine grinding of pigments places high demands on the machine technology to be employed. The finest, absolutely gritfree granulation, lowresidue processing with minimal contamination, as well as fast, thorough cleaning when switching products are the minimum requirements.
