Tempera, also known as egg tempera, is a painting medium that consists of pigments mixed with a water-soluble binder, usually egg yolk. It is a fast-drying and long-lasting medium, with examples from the first century AD still existing today. The process of creating tempera involves hand-grinding dry powdered pigments into a binding agent such as egg yolk, milk, or plant gums. The paint mixture must be constantly adjusted to maintain a balance between a greasy and watery consistency by modifying the amount of water and yolk. Tempera dries quickly, making it challenging to blend edges, and artists must work section by section. The paint is water-resistant but not waterproof, and it cannot be stored for future use as the yolk thickens and the water evaporates over time.

Tempera, also known as egg tempera, is a permanent, fast-drying painting medium
The paint mixture must be constantly adjusted to maintain the right consistency, and as tempera dries, more water can be added. While egg tempera is water-resistant, it is not waterproof. It dries quickly, which can make blending challenging, as the paint must be worked section by section. This rapid drying also means that tempera paint cannot be stored and must be used within a single painting session.
The process of creating egg tempera paint involves separating the egg yolk from the white and removing the yolk sac. The yolk is then mixed with a small amount of water and stirred. This mixture is combined with the dry pigment to create a paste, and additional water or alcohol can be added to adjust the consistency. Finally, more egg yolk is added to the paste, and water is used to thin the medium as needed.
Tempera has been used for centuries, with examples of tempera paintings dating back to the first century AD. It was a primary method of painting until around 1500 when it was replaced by oil painting. Tempera colours do not change over time, unlike oil paints, which darken and become transparent with age. Tempera is typically applied in thin, semi-opaque, or transparent layers, allowing for great precision and fine details.

The paint mixture must be constantly adjusted to balance its consistency
Tempera, also known as egg tempera, is a permanent and fast-drying painting medium that consists of pigments mixed with a water-soluble binder, usually a glutinous material like egg yolk. The paint mixture must be constantly adjusted to balance its consistency.
The process of creating egg tempera involves hand-grinding dry powdered pigments into a binding agent or medium, such as egg yolk. The white of the egg and the membrane of the yolk are typically discarded, and the yolk is diluted with water. It is important to note that the amount of water added depends on the pigment's properties, aiming for a smooth paste similar to toothpaste. The ratio of yolk to water is typically around 1:3, but some recipes suggest using white wine instead of water, adjusting the proportions accordingly.
The key challenge in mixing egg tempera is achieving the right consistency. Adding too much egg yolk will result in a greasy appearance, while too little will make the paint chalky. To strike a balance, artists adjust the amounts of water and yolk, constantly fine-tuning the mixture. As tempera dries, the artist adds more water to maintain the desired consistency and counterbalance the thickening effect of the yolk when exposed to air.
Egg tempera dries quickly, which can make blending edges challenging. Artists must work section by section, applying different values of colour near or on top of each other to create transitions in hue. This technique is similar to working with coloured pencils, where strokes of colour are layered to achieve the desired effect.
Egg yolk has been used historically by Old Masters like Botticelli and Leonardo da Vinci, who sought to refine the oil paint medium. The addition of egg yolk altered the behaviour of oil paints, improving brushability, enabling intricate impasto effects, and enhancing resistance to environmental conditions.

Tempera colours do not change over time, unlike oil paints
Tempera, also known as egg tempera, is a permanent, fast-drying painting medium that consists of pigments mixed with a water-soluble binder, usually a glutinous material like egg yolk. It is created by hand-grinding dry powdered pigments into a binding agent or medium, such as egg yolk, milk (casein), and various plant gums. The paint mixture must be constantly adjusted to maintain a balance between a "greasy" and "watery" consistency by modifying the amount of water and yolk.
The colours of tempera paints do not change over time, unlike oil paints, which tend to darken, yellow, and become transparent with age. Tempera paints are long-lasting, with examples from the first century AD still retaining their original colours. This permanence is due to the nature of the tempera medium, which dries quickly and adheres best to absorbent grounds with a lower oil content than the tempera binder used.
The process of creating tempera involves separating the egg yolk from the egg white and puncturing the yolk's membrane to drain off the liquid inside. The egg yolk is then diluted with water and mixed with the powdered pigment. To ensure proper binding, the paint can be dried on a plate, and if it curls when scraped with a razor blade, the mixing was successful.
Tempera has a cooler colour range than oils and cannot achieve the same deep, warm blacks or colour saturation as oil paints. It is applied in thin, semi-opaque, or transparent layers, allowing for great precision with traditional techniques that utilise numerous small brush strokes in a cross-hatching technique. While tempera dries rapidly, providing a smooth matte finish, it cannot be stored once prepared and must be used promptly.
While oil paints eventually superseded tempera as the preferred medium, tempera has experienced revivals and continues to be used traditionally in countries like Greece and Russia for painting Orthodox icons.

Tempera dries quickly, making it difficult to blend edges
Tempera paint, also known as egg tempera, is a permanent, fast-drying painting medium consisting of pigments mixed with a water-soluble binder, usually egg yolk. Tempera paint dries quickly, often within just a few minutes of application. This rapid drying makes it difficult for artists to blend colours, as the paint becomes immovable shortly after it is laid down.
The fast-drying nature of tempera paint can be a challenge for artists, limiting their ability to create smooth transitions between colours. It sets almost immediately, making it hard to manipulate or blend with other colours. This is in contrast to oil paint, which dries slowly, allowing artists to blend colours easily over a longer period.
However, the quick-drying property of tempera paint also offers some advantages. Artists can create defined brush strokes and achieve sharp edges in their artwork. The paint can be applied in thin, semi-opaque, or transparent layers, allowing for great precision when used with traditional techniques that involve numerous small brush strokes in a cross-hatching technique.
To blend colours with tempera paint, artists need to mix different values of colours and apply them near or on top of each other to create transitions in hue or value. This is similar to working with coloured pencils, where strokes of colour are applied to create blends. Fine details can be added with a liner brush, helping to delineate objects and create areas of light and dark.
Overall, tempera paint's quick-drying nature can be both advantageous and challenging for artists, requiring careful planning and technique to achieve the desired effects.

Tempera is a water-based painting medium made by blending egg yolks with water
Tempera is a water-based painting medium that uses a mixture of egg yolks and water. It is a permanent, fast-drying medium that was widely used before 1500 when oil painting became more popular. Tempera is created by hand-grinding dry powdered pigments into a binding agent, such as egg yolk, and then diluting it with water. The ratio of yolk to water is typically 1:3, but some recipes substitute water with white wine in a 1:2 ratio.
The process of creating tempera paint involves separating the egg yolk from the white and then breaking the yolk sac with a pin. The contents of the yolk sac are then mixed with water and stirred. It is important to ensure that none of the egg whites are included in the mixture as this can affect the paint's ability to adhere to surfaces. The addition of a small amount of vinegar can also act as a preservative.
The paint mixture must be constantly adjusted to maintain the right consistency, balancing between greasy and watery. As tempera dries, water can be added to maintain consistency and balance the thickening of the yolk. However, once prepared, the paint cannot be stored as it will cure and thicken, making it difficult to paint with.
Tempera paint dries quickly, allowing artists to apply multiple layers in a single session. It is often used for detailed work and fine, linear brushstrokes. The paint dries to a slightly glossy finish when the right amount of egg yolk is used. Tempera is usually applied in thin, semi-opaque, or transparent layers, and it is important to work section by section due to its fast-drying nature.
