Definición y Significado de "fresco-secco"

What is "fresco-secco"?

Fresco-secco is a painting technique where colors mixed with a glue-like substance are applied to dry plaster on a wall. Unlike true fresco, where colors are painted on wet plaster, fresco-secco allows for more detail and correction, but it is less durable because the paint stays on the surface rather than becoming part of the wall. This method has been used in different historical periods, especially in ancient Egyptian and Renaissance wall paintings.
