Examination. Microscopic examination (123) can identify the fibers present ia the pulp (124). Inks, watercolor pigments and media, etc, are analyzed similarly to the pigments and media for paintings. However, sample removal tends to be far more disfigutiag and hence constitutes an even more restrictive factor. Watermarks are studied with the aid of beta-radiography. Examination ia iafrared illumination can assist ia the reading of documents of which the ink has faded. 

Cobalt is used as a blue phosphor in cathode ray tubes for television, in the coloration of polymers and leather goods, and as a pigment for oil and watercolor paints. Organic cobalt compounds that are used as colorants usually contain the azo (51) or formazon (52) chromophores.

It can be seen that, historically, a paint is anything that contains pigment, a colored, powdered substance, and a binder, a material that evenly disperses the pigment and adheres to a surface when the paint is applied and then dries. A pigment combined with a binder makes a paint. A medium is used to dilute a paint. The composition of watercolor, egg tempera, oil, and acrylic paints is discussed in this chapter.

Watercolor is considered by many to be more like a stain on the paper than a paint that lies on the surface of the paper. Colors are applied in thin washes and can be built up, color on top of color. The white of the paper shining through beneath the paint adds a crisp effect to this medium. White paint is not used to lighten colors this would create an opaque rather than a transparent effect. Colors are lightened by the addition of water.

Poster paints come in limited colors. They can have a chalky appearance. Watercolors cannot be used to produce actual texture. Some of the colors fade when exposed to sunlight. Colors can be lifted off to lighten an area. Colors can be applied so they are transparent to light. Acrylic paints are easily painted over when dry. However, they are sometimes difficult to blend. 

If watercolor paints are in dry cake form, the dry cake must be mixed with water to make a paint. Improper mixture can result in a heterogeneous mixture. When acrylic and poster paints are diluted with water, heterogeneous mixtures can also result. 

Artists use many different types of paper to create their artwork. Artists using watercolor, for example, paint on paper that is specially designed for this medium. Watercolor paper may be rough in texture, medium textured, or smooth. Rough- and medium-surfaced papers are called cold press (CP) paper because the textured surface is effected by rolling the newly formed sheet through a set of cold rollers. Smooth-surfaced paper is called hot press (HP) paper because the newly formed sheet is rolled through a set of hot rollers to effect a smooth surface. 

Stretching watercolor paper as described below produces a paper that is not distorted when an artist applies water to the paper to paint a wet-into-wet painting and then lets the artwork dry.
