When egg tempera is applied thickly to a painting, it can cause the paint to crack. This is because the egg tempera dries quickly and doesn't have time to cure properly. If the paint is applied too thickly, the egg tempera will also start to yellow.
What are the properties of egg tempera that make it unsuitable for thick application?
Egg tempera is an aqueous medium and as such it dries very quickly. This is both an advantage, in that one can work wet-into-wet and produce fresh, luminous colors, and a disadvantage, in that it can be difficult to apply in a smooth, even layer when working on a large surface.
The other main property of egg tempera that can make it challenging to work with is its transparency. Egg tempera dries to a matte finish and is quite transparent, so it is important to build up colors slowly and layers must be allowed to dry completely before adding more colors on top. If colors are applied too thickly, they will dry with a grainy finish.
How does egg tempera compare to other painting mediums?
Egg tempera is an emulsion paint consisting of powdered pigments bound in egg yolk. It has been used as a painting medium since the time of the ancient Egyptians, and its popularity spread throughout the Roman Empire and the Byzantine Empire. Egg tempera was the primary medium used by Early Renaissance painters such as Botticelli, Ghirlandaio, and Perugino.
egg tempera dries very quickly, usually within minutes. This makes it ideal for use in fresco painting, as it minimizes the risk of the paint drying before it can be applied to the wall. egg tempera also has a very delicate, matte finish that is less susceptible to damage than paintings done in oil paint.
However, egg tempera does have some drawbacks compared to other painting mediums. It is not as forgiving as oil paint, and it can be difficult to achieve subtle gradations of color. It can also be harder to control the consistency of the paint, as the egg yolk can separate from the pigments if not properly mixed. Overall, egg tempera is a versatile and resilient medium that has been used by artists for centuries.

Frequently Asked Questions
When was egg tempera used in art?
Egg tempera was used in art from the 14th century onwards.
What size brush do you use for egg tempera?
For detailed applications, 1 or 2 hairs wide brush is often used.
Can you paint on egg tempera?
Yes. Egg tempera dries quickly and is easy to work with, but the painting time is more like that of oils since the layers do need to cure, or oxidise, so they won't be picked up by later layers.
Can you use egg tempera on wood?
Yes, egg tempera can be used on wood. However, you will need to follow a few guidelines in order to avoid damage: 1. Use a primer that is specifically designed for egg tempera. Many primers are formulated with walnut shell oil, which helps keep the paintable surface smooth and allows the paint to adhere better. 2. Apply your paint very thinly – just enough to cover the surface without flooding or going runoff. This will ensure that your painting will not peel or chip when it is finished. 3. Do not over-paint; if there are areas that are still missing color, simply touch them up with a dry brush once the entire painting has been completed. Do not use a wet brush in order to avoid creating water spots.
How do you make egg tempera?
Egg tempera is a painting medium made from powdered pigment, eggs and water. It is easy to mix and dries quickly, so you will need to work quickly while it is still wet.
