What is tempera gesso?
What is tempera gesso?
Chalk gesso is a white plaster-like priming that is applied to a rigid substrate (i.e. some sort of board) to make a smooth, hard yet absorbent surface for egg tempera painting. It can also be used under oil paintings.
What was used to paint on for the egg tempera technique?
Most egg tempera paintings from centuries past were created on wood panel. Poplar wood was most commonly used. But since this wood warped over time, panels were constructed by combining several slats together. A high level of craftsmanship and skill was required just to prepare the surface.
How was tempera paint made?
True tempera is made by mixture with the yolk of fresh eggs, although manuscript illuminators often used egg white and some easel painters added the whole egg. Other emulsions—such as casein glue with linseed oil, egg yolk with gum and linseed oil, and egg white with linseed or poppy oil—have also been used.
What is traditional gesso made of?
“Gesso”, also known “glue gesso” or “Italian gesso” is a traditional mix of an animal glue binder (usually rabbit-skin glue), chalk, and white pigment, used to coat rigid surfaces such as wooden painting panels as an absorbent primer coat substrate for painting.

Does tempera paint have eggs?
Tempera paints have an egg base that can trigger an egg allergy. Finger paint sometimes contain wheat, milk, corn, or oat.
Did Michelangelo use egg tempera?
For example, most surviving panel paintings attributed to Michelangelo are executed in egg tempera, an exception being his Doni Tondo which uses both tempera and oil paint. Oil replaced tempera as the principal medium used for creating artwork during the 15th century in Early Netherlandish painting in northern Europe.
Why does tempera paint crack?
Since tempera initially dries through the relatively rapid evaporation of its water content, if too dense a layer of impasto paint is applied, it can crack as it shrinks (akin to what a dried-out lake bed looks like).
Can you make tempera paint permanent?
Using three equal parts of yolk and distilled water, and one part linseed oil, make your medium to hold the pigment. Mix the pigment paste into the yolk medium to make permanent tempera paint. On the palette, mix pigment into the yolk medium a little bit at a time.
Why do artists use egg tempera?
Why use egg tempera? Tempera is more transparent than oil and holds less pigment, which allows light to penetrate through it and reflect off the white surface of the gesso below. Another advantage of egg tempera is that, unlike oil paintings, it is resistant to light, and its colours do not darken or change with age.
What can I substitute for gesso?
In short, the best alternatives for gesso are either commercial acrylic primers or Clear Gesso. It is also possible to paint directly on the surface without any primer or, if a cheap alternative to gesso is needed, then gesso can be easily made at home with ingredients that can be bought almost anywhere.
What’s the best way to put tempera on gesso?
A drop or two of clove oil or wine can be added to impart a pleasant smell and retard spoilage. Tempera should be applied over a glue gesso on a rigid panel, (see our recipe for Artist’s Gesso ). Remember that tempera dries quickly. Be sure to clean all tools well in hot, soapy water.
What kind of glue do you use to make gesso panels?
Day One: Put ½ ounce of rabbit skin glue and 8 ounces (1 cup) water in the upper pot of a double boiler and stir. This glue will be used to prime your panel. Put another 1 ounce of glue and 16 ounces (2 cups) water in a second container and stir.
What happens to gesso when you put it in the fridge?
Sitting allows air bubbles to dissipate and the inert white substance to be more fully absorbed by the glue. The result is a smoother gesso. The gesso must be refrigerated while it sits, or the glue may go bad. Gesso takes on the consistency of very hard Jell-O when cool but redissolves readily when warmed.
How long does it take to make a gesso panel?
Four to six days from start to finish are required to create a true gesso panel using a homemade gesso recipe. Only one (or two) of these days is a full day. The other days involve anywhere from a few minutes to an hour of work.
