Recipe: Tempera Grassa/ Rich Tempera

The word Tempera comes from Latin „temperare“ and means “to make mild” or “to control” which is probably referring to the fact that tempera paint combines materials which are usually unmixable. Mixing agents or emulsifier are used in order to blend resin, oil and water-dilutable colors without the use of odorous solvents. Tempera paint can be used for nuanced art work since it is hardly runny. The dry paint is water-resistant.

Processing

Stir the egg with a mixer or whisk until smooth, then, while constantly stirring add the walnut oil drop by drop. Step 1#113: Stir the egg with a mixer or whisk until smooth, then, while constantly stirring add the walnut oil drop by drop.
Heat the Larch Turpentine in a water bath (#62000) to 40 °C (= 104 °F), and add it drop by drop to the mixture, while stirring constantly. Step 2#140: Heat the Larch Turpentine in a water bath (#62000) to 40 °C (= 104 °F), and add it drop by drop to the mixture, while stirring constantly.
Stir the pigment of your choice into the rich egg tempera (binder) in a mortar or on a plate, and grind until the fluid has a viscosity like yogurt. Step 3#148: Stir the pigment of your choice into the rich egg tempera (binder) in a mortar or on a plate, and grind until the fluid has a viscosity like yogurt.

Note

For egg tempera, you should only use distilled or demineralized water. Tap water can cause flocculation of the mixture. Boiling the water before use will prolong the stability of the paint. As a preservative, you can add a drop of Clove Oil (#73700).
