Final answer:
The statement that when pigment is applied to wet lime plaster, a buon fresco is created is true. The buon fresco technique involves the chemical bonding of pigment with wet plaster, making the painting a part of the wall and providing durability.
Step-by-step explanation:
When pigment is applied to wet lime plaster, a buon fresco is indeed created, making the statement true. The buon fresco technique consists of painting in pigment mixed with water directly onto a layer of wet, fresh lime mortar or plaster. As the lime plaster sets and dries, it reacts chemically with the carbon dioxide in the air. This reaction causes the pigment particles to become chemically bonded to the plaster, effectively turning the painting into an integral part of the wall itself. This method is more stable and durable compared to fresco secco, where the pigment is applied to dry plaster.
The term 'buon fresco' is also known as 'true fresco' and is a hallmark of Renaissance art, but it has been utilized by artists for millennia. Notable fresco paintings can be found throughout history, especially within the remnants of ancient Roman architecture and during the Renaissance, where artists like Michelangelo and Leonardo da Vinci used the technique to create some of their most famous works.
