Buon fresco ("true" fresco)
"The bare wall was first dampened and coated with a layer of coarse lime plaster, called arriccio, on which the design was drawn or brushed in red earth pigment (sinopia). The overall composition was painted in sections known as giornate—Italian for “a day’s work.” Each of these sections was composed of a smooth plaster layer called intonaco. Pigments diluted in water were applied directly to the wet intonaco; as the plaster dried, a chemical reaction bound the pigment to it." (Heilbrunn Timeline of Art History)
Fresco secco (dry fresco)
"Embellishments applied to a dry wall—fresco a secco (secco is the Italian word for dry)—are far less durable, as the paint tends to flake off over time. Fresco is vulnerable to moisture and may be damaged in a cool, damp environment." (Heilbrunn Timeline of Art History)
Paints composed of pigments ground to an extremely fine texture in an aqueous solution of gum Arabic or gum tragacanth. The absence of white fillers, such as those in gouache, creates a medium with luminous transparency. (MoMA Glossary of Art Terms)
