What is the difference between buon fresco and secco fresco?
A.) Buon fresco is a type of painting on plaster in which paints are water-based, and fresco secco is a type of painting on plaster in which the paint is oil-based.
B.) Buon fresco is a method of painting on plaster in which the plaster is still wet, and fresco secco is a method of painting on plaster in which paint is applied after the plaster is already dried.
C.) Buon fresco is a method of painting on plaster in which paints are oil-based, and fresco secco is a method of painting on plaster in which the paint is water-based.
D.) Buon fresco is a method of painting on plaster in which paint is applied after the plaster is already dried, and fresco secco is a method of painting on plaster in which the plaster is still wet.
The Correct Answer and Explanation is:
The correct answer is b.) Buon fresco is a method of painting on plaster in which the plaster is still wet, and fresco secco is a method of painting on plaster in which paint is applied after the plaster is already dried.
Explanation:
Buon fresco and fresco secco are two different techniques used in fresco painting, an ancient art form where pigment is applied to a wall or ceiling surface covered in plaster. These methods differ in terms of the timing of the paint application and the condition of the plaster.
In buon fresco, also known as “true fresco,” artists apply pigments mixed with water onto a fresh, wet plaster surface. As the plaster dries, it undergoes a chemical reaction called carbonation, which bonds the pigment to the plaster. This process creates a durable, long-lasting image because the pigments become an integral part of the wall. Since the pigments sink into the wet plaster, buon fresco paintings are particularly resistant to fading and peeling over time. However, the technique demands precision and speed, as artists must complete their work before the plaster dries.
On the other hand, fresco secco is a technique where paint is applied to dry plaster. In this case, the artist mixes the pigments with a binding medium, such as egg yolk, glue, or oil, to adhere to the dry surface. While fresco secco allows for more flexibility, since artists don’t need to work within the limited time frame of wet plaster, the resulting images are generally less durable. Because the pigments sit on the plaster surface rather than bonding with it, fresco secco paintings are more prone to flaking and fading over time.
Historically, artists have often combined these techniques. They might use buon fresco for large color areas and fresco secco for details, as seen in some Renaissance works. Both methods have unique characteristics, but buon fresco is typically favored for its durability and integration with the wall surface.
