Fresco Painting is a mural painting technique that involves painting with water-based paint directly onto wet plaster so that the paint becomes an integral part of the plaster. The word fresco is an Italian for “fresh”. Fresco painting makes use of chemical reaction that causes color pigment to crystalize within the plaster as it dries. As the plaster dries, carbon dioxide in the air turns the lime to calcium carbonate, crystalizing the pigments. The color then becomes part of the plaster itself. The process of forming a carbonate is sometimes referred to as “carbonation”, this term usually refers to the process of dissolving carbon dioxide in water. Calcium carbonate and natural pigments make the medium of Fresco the most environmentally safe medium. Only pigments that resist the action of lime can be used. The pigments are usually earth color. Frescoes have been painted for hundreds and hundreds of years. What is the role of carbon dioxide in air in Fresco Painting?

What is the role of carbon dioxide in air in Fresco Painting? What type of catalytic mechanism (heterogenous or homogenous) exist in Fresco painting? Why?
Definition Definition Transformation of a chemical species into another chemical species. A chemical reaction consists of breaking existing bonds and forming new ones by changing the position of electrons. These reactions are best explained using a chemical equation.
