The fresco is a very ancient painting technique that consists of painting on fresh plaster with pigments usually of mineral origin, slightly diluted in water. Through the chemical process of carbonation, the colour merges with the plaster thus allowing the paint to resist water and wear over time.
The colour that is laid on the still wet plaster must belong to the oxides category, so that it does not interfere with the carbonation reaction of the lime.
