What is fresco and its use in interior decoration?

• A. Painting on wet plaster
• B. Painting on dry plaster
• C. Mosaic on walls
• D. Stained glass

Answer: (A)

Fresco means painting onto plaster while it is still wet, so the pigment becomes part of the wall as the plaster dries. In interior decoration, this allows large murals to be integrated directly into walls and ceilings, producing durable, seamless surfaces ideal for grand schemes in churches, palaces, and public buildings. The moisture in the plaster binds the pigment chemically, giving longevity and a matte, unified finish that can withstand time and cleaning. Painting on dry plaster is a related technique (fresco secco) but not the classic fresco, and mosaics or stained glass are different media altogether used for decorative effects in interiors.
