Dispersing Technology

The pigment content is chosen such that after dispersion a non flowable pigment paste is generated. Normally a content of approximately 30% organic pigment and 70% inorganic pigment is necessary to obtain these conditions. The dispersing time is about 30 min.; a dissolver or an equal dispersing device is used. 2.

PIGMENTS Natural Pigments

Rublev Colours pigments are made directly from mineral and organic sources. Our geologist, who has many years experience selecting minerals for pigments, travels to distant locations, and hand selects mineral ores for use in our pigments. We process the minerals by pulverizing, grinding and levigating for use as fine artists’ pigments.

handprint : synthetic inorganic pigments

synthetic inorganic pigments. Synthetic inorganic pigments are created through chemical manufacturing rather than by grinding and washing clays or minerals taken directly from the earth. The techniques for producing these substances on an industrial scale were developed after 1800, making them the first modern synthetic pigments of importance to artists.

Pigment Wikipedia

Pigments appear colored because they selectively reflect and absorb certain wavelengths of visible light. White light is a roughly equal mixture of the entire spectrum of visible light with a wavelength in a range from about 375 or 400 nanometers to about 760 or 780 nm. When this light encounters a pigment, parts of the spectrum are absorbed by the pigment.
