Paper Restoration in Artworks and Archival Documents
3 Units
Instructor: Profs. Manuela Belli (first 2 weeks) and Laura Chignoli (second 2 weeks)
COURSE STRUCTURE
Mornings: Theoretical Lectures 3 hours (SG206A)
Afternoons: 4 hours workshops (SG206B)
The courses include a study visit to Fabriano Paper Museum and special sessions with an external teachers.
Course 1 and 2 Descriptions
REQUIREMENTS: Courses SG206A (theory) and SG206B (workshop) must be taken together.
Course 1
Paper Media and Restoration Methods for Artworks
This lecture and workshop course on the restoration of paper media aims to give an overview of the field, including instruction on the nature and history of paper, the traditional methods of paper making, the different artistic techniques, the processes of deterioration over time, and the various methods of handling and mounting, conservation and restoration of artworks on paper.
Students learn the following: the material nature and the various typologies of paper (both traditional and new), the artistic techniques, the various agents and processes of deterioration and how they impact both paper and drawing media and the various methods of conservation and restoration to counteract them.
Course 2
Handwritten and Printed Archival materials Restoration Methods
The second course is a lecture and workshop where students focus on archival documents and original manuscript material from local historic archives (16th to 19th centuries), and learn their evolution in history. The following subjects are also treated or practiced: decoration of paper, dry cleaning, gentle or local washing, mending tears in paper, infilling loses, lining weak paper structures, deacidification, flattening, simple sewing and proper long-term conservation of archival materials.
The course includes a study visit to “Santo Chiodo” depot (Spoleto) and special session with an external teacher.
[The workshop also includes work on the digitization of the San Gemini Historic Archives.]
Students learn the following: the material nature and the various typologies of inks, writing, printing processes, the structure of archival bindings, the various agents and processes of deterioration of paper documents and how they impact both paper and bindings or cases and the various methods of conservation and restoration to counteract them.
Course Objectives
These courses are aimed at two types of students: those planning to become restorers and those planning to manage paper-based resources in libraries, archives or museums. For those planning on a career as a restorer, this is a good introduction to the field to be followed up by further education. For those planning to manage paper-based resources, it is a good overview of the field and offers insight and experience on the safe storage and conservation of paper materials.
