Malta. Donizetti per affresco a carbonatazioni cumulative. Donizetti Fresco Lime Plaster with Cumulative Carbonatations

Ten years of experimental trials have allowed Mario Donizetti to complete his technical research on frescoes and today he announces that the classic fresco lime plaster has been surpassed by his new lime plaster because the latter allows to carbonatate, even after years, colours spread with water on the same plaster, without altering the chromatic value of the pigments. The chemical process is identical to that of the carbonatation of the classic lime plaster of millenary tradition, but this new lime plaster also allows the accumulation of layers of carbonatated pigments which are complementary to the first application.
