Egg Tempera: Binder Basics For Artists

what is the vehicle binder of egg tempera painting

Tempera, also known as egg tempera, is a permanent, fast-drying painting medium that was the primary method of painting until 1500 when it was replaced by oil paint. The vehicle for egg tempera is a combination of egg yolk and distilled water, with the egg yolk acting as a binder to make the paint stick and hold the pigment together. The word tempera comes from the verb temper, meaning to bring to a desired consistency. The paint mixture has to be constantly adjusted to balance its consistency as tempera dries. Different recipes for the paint include additives such as oil, wax emulsions, and wine.

Egg yolk is the binder

Egg tempera is made by combining pigments with a vehicle, which is a combination of egg yolk and distilled water. The egg yolk acts as the binder, holding the pigment together and allowing the paint to move. The process of making egg tempera paint involves separating the egg yolk from the egg white, drying the egg yolk, and then mixing it with distilled water and pigment. The paint mixture must be constantly adjusted to maintain a balance between a "greasy" and "watery" consistency by modifying the amounts of water and yolk.

Egg tempera has been used for centuries, with examples from the first century AD still in existence. It was the primary method of painting until after 1500 when it was replaced by oil painting. Egg tempera is a durable form of the medium, generally unaffected by humidity and temperature, and dries quickly to form a tough film. It is also relatively inexpensive.

Artists in ancient Egypt, Greece, and Rome were aware of the binding properties of eggs, and during the Middle Ages, egg tempera became the primary painting medium. It was used on various surfaces, including stone, wood, paper, and canvas, and was particularly popular for panel paintings and illuminated manuscripts in Medieval and Early Renaissance Europe.

The recipes for egg tempera are infinite, and artists have experimented with different mixtures and additives to achieve the desired consistency and effects. For example, vinegar or white wine can be added as a preservative, and other emulsions such as casein glue with linseed oil, egg yolk with gum and linseed oil, or egg white with linseed or poppy oil have also been used.

Water is the solvent

Egg tempera is a permanent, fast-drying painting medium consisting of pigments mixed with a water-soluble binder medium, usually a glutinous material such as egg yolk. The egg yolk is the binder, and the water is the solvent. The two are combined to make a vehicle for the paint, which is what makes the paint move and allows it to hold the pigment together.

To prepare the paint, the yolk of an egg is separated from the white and dried. It is then mixed with the dry pigments and diluted with water. The ratio of yolk to water is usually 1:3, but this varies depending on the pigment. The paint mixture must be constantly adjusted to maintain a balance between a "greasy" and "watery" consistency. As tempera dries, the artist will add more water to preserve the consistency and to balance the thickening of the yolk on contact with air.

Egg tempera was the primary method of painting until after 1500 when it was superseded by oil painting. It was used to decorate the early Christian catacombs and to paint icons, a tradition in the Eastern Orthodox Church that is still in use today. It was also the main medium used for panel painting and illuminated manuscripts in the Byzantine world and Medieval and Early Renaissance Europe.

Pigments are the colour

Pigments can be acquired from various resources, including plants, naturally occurring minerals, and even insects. However, pure pigments are available through most online art supply retailers. The pigment is mixed with the binder to create a paste.

When preparing the egg yolk, it is important to separate it from the egg white, as the albumen in the egg white prevents the paint from adhering well to the panel surface. The yolk can be dried by rolling it on a paper towel or passing it between your hands. It is then mixed with distilled water and added to the pigment.

Some pigments require more binder than others. The paint mixture must be constantly adjusted to maintain a balance between a "greasy" and "watery" consistency. As tempera dries, the artist may add more water to preserve the consistency.

The colours of an unvarnished tempera painting resemble a pastel, but the colour deepens if a varnish is applied. Tempera colours do not change over time, unlike oil paints, which darken and yellow with age.

The vehicle is a combination of egg yolk and water

The vehicle in egg tempera painting is a combination of egg yolk and water. The egg yolk acts as a binder, holding the pigment particles together. This mixture of egg yolk and water is then combined with a pigment to create the final paint. The word "tempera" is derived from the verb "temper", which means "to bring to a desired consistency". This process of "tempering" involves mixing dry pigments with a binding and adhesive vehicle.

In the context of egg tempera, the egg yolk serves as the binder, while water is the solvent or vehicle. The egg yolk is first separated from the egg white, as the white part can hinder the adhesion qualities of the paint. The yolk is then dried, and a small amount of water is added to create the desired consistency. The ratio of yolk to water is typically around 1:3, but this can vary depending on the specific recipe and the type of pigment being used.

Egg tempera has been a long-standing and durable form of painting, with examples of its use dating back to the first century AD. It was the primary method of painting until around 1500 when oil painting became more prevalent. The binding properties of egg tempera make it particularly effective, and it is generally unaffected by humidity and temperature changes.

The process of creating egg tempera paint involves mixing the egg yolk and water to form a binder, which is then combined with the pigment. This pigment provides the colour and can be derived from various sources, including plants, insects, and natural minerals. Today, synthetic pigments are commonly used and can be purchased from art supply stores.

Artists have the option of mixing the vehicle with the paste before starting their painting or doing so directly on a palette during the painting process. This flexibility allows for different approaches to applying the tempera paint. The traditional method involves building up layers of small, translucent strokes over an underpainting, creating a unique depth and texture to the final artwork.

The paint is applied in layers

Egg tempera is a permanent, fast-drying painting medium consisting of pigments mixed with a water-soluble binder medium, usually a glutinous material such as egg yolk. The paint is prepared by mixing the binder with the pigment. The solvent used in this case is distilled water.

Glazing is the process of layering translucent applications of colour over other areas of colour. Each glaze slightly alters the colour, allowing the artist to make subtle changes in value, intensity, and hue. Glazing is also a popular technique with oil painting, watercolour, and acrylics.

Egg tempera cannot be layered in the same way as oil paint, and cannot be used to build impasto (texture). It dries very quickly, meaning that artists must work on a small area at a time, using small strokes and cross-hatching. This makes it best suited to fine, detailed small work using fine brushes, such as portraits.

Artists must also be careful not to apply tempera paint too heavily and quickly, as it can crack over time. Instead, it is best to apply the paint with layers.
