37489 - Processes in Conservation

Course Unit Page

Academic Year 2019/2020

Learning outcomes

At the end of the course the Student will acquire knowledge: - to recognize constituent materials and forms of alteration and/or deterioration of the work of art, - to implement the most appropriate investigations to assess the state of conservation, - to provide the conservator-restorer with useful information for the preparation of an adequate intervention project using a dialectical and interdisciplinary approach. The student will be able to: - recognize techniques and constituent materials of artefacts (mainly polychrome wooden sculpture and easel paintings) - identify the main causes and phenomena of degradation - identify suitable analytical methodologies - acquire basic knowledge on materials and restoration techniques - learn methods and tools for preventive conservation, with reference to light, temperature, and R.H. - improve capacity to team work - apply the concepts learned, develop a critical and ethical approach to conservative intervention, and know how to communicate through specific terminology the data collected by transferring them into a treatment proposal or a condition report - interact with the professional figure of the Conservator-Restorer in a dialectical and interdisciplinary relationship

Teaching methods

The course will consist of:

classroom lectures with PowerPoint presentations and videos,

insights on specific articles

practical tests on mock-ups or artifacts available in the laboratory,

discussions and comparisons during class hours,

visits at museums, collections and exhibitions.

Assessment methods

The exam consists of:

- production of a report on a topic developed during the course in pps format, to be sent a week before the exam date (pdf format);

- a written test: 4 multiple choice questions and 2 open answer questions;

- a discussion on the topics of the course, aimed at evaluating the theoretical knowledge of the subject, taking a specific language and acquiring an organic vision of covered topics.

The final grade is determined with the following percentages:

Written exam: 20% multiple choice questions, 50% open answer questions

Presentation.pps: 30%

The final assigned grade will be determined with the evaluation of the activity carried out during the hours of the course and the evaluation of the oral test.

Good or excellent grades can be achieved by students who demonstrate a critical knowledge of the subject, who are able to apply theoretical concepts to practical examples and make use of an appropriate language. Mostly mnemonic knowledge, limited abilities of synthesis and analysis and imprecise language lead to grades ranging from discrete to sufficient. Important gaps, inappropriate language, lack of an overview of the topics covered will inevitably lead to a barely adeguate grade or to a negative evaluation.

Teaching tools

PC, projectors, on-site visits.
