Learning Objectives

EDUCATIONAL OBJECTIVES:

The lessons will be introduced by the theory and history of the treatment of the gap over the centuries, starting from the medieval approach, the evolution over the centuries, arriving at the determination of the twentieth-century Restoration Cards and the current different methodological theories.

Different stuccos will be explained and prepared for the integration of gaps in works of art, both natural and synthetic.

The main pictorial integration techniques used for the pictorial restoration of paintings on canvas, wood and wooden sculptures will be explained and illustrated: hatching; selection and chromatic abstraction and integration of abrasions with lowering of tone and glazing.

Program

Module I: Introduction (9 hours)

Theory: History and theory of lacuna treatment. (9 hours)

Module II: Stuccatura (32 hours)

Theory: Methodological introduction of the concept of stucco. Comparison between the Florentine and Roman methods in the treatment of lacuna. Case studies. (5 hours)

Presentation of the characteristics required of stuccos.

Laboratory: Preparation of different stuccos, both traditional (Bologna plaster and animal glue) and innovative (Aquazol, Plextol, Arbocel). (5 hours)

Preparation of small tablets with different types of stuccos. (5 hours)

Stuccatura of paintings on canvas and panel and material processing of the surface. (17 hours)

Module III: Pictorial integration (84 hours)

Theory: Methodological introduction of hatching (ICR method) and chromatic selection (OPD method). Comparison between the Florentine and Roman methods in the treatment of the gap in different case studies: from the Annunciation by Antonello da Messina to the Altarpiece of San Marco by Beato Angelico. (12 hours)

Laboratory: Preparation of materials for watercolor retouching, Aquazol and Laropal A-81. (15 hours)

Exercises on techniques for pictorial integration, both on paper and on tablets made in the II module of stuccoing. (20 hours)

Pictorial integration of paintings on canvas and panel and wooden sculptures present in the laboratory. (37 hours)

Bridging Courses

Paper exercises of the line for hatching in laboratory courses I, II year.

Learning Achievements (Dublin Descriptors)

The aim of the course is to provide students with all the tools for a critical reading of the gaps present in the works and to be able to implement the best methodological choices; as well as having mastery of the various materials and laboratory equipment. Understanding of the different methods of pictorial integration of the gaps.
