Learning Objectives

Give students the necessary tools in order to face the design of a restoration project, to be able to work on an artwork on canvas from the structural point of view, and finally to give the necessary tools to know how to handle the new technologies in the field of restoration.

Program

Analysis of the rheological behavior of the constituent materials (12 hours)

  • mechanical properties of wood, of canvas, of the preparation, of the paint layers, of the physical-mechanical behavior of materials, of external factors and theirs influence in the behavior.

The tension of the paintings on canvas - theoretical part: (19 hours)

  • The constant stress and the relationship canvas-frame.
  • Analysis and variations of the distributions of the tensions within a painting in relation to the types of frame that we use.
  • Traditional methods and history of the tension of the paintings on canvas.
  • Of the importance of creating a floating system with priority on the shrinkage of the support stretcher.
  • Measures to give uniformity to the forces applied to the painted textile.
  • The stretcher as a tool of preventive conservation: recent solutions to balance the forces.
  • Models and mechanisms for self-expansion frames and floating self-adaptive frames.
  • Low impact solutions for the reuse of the original frames.
  • Recovery of ancient frames and study of reticular frames.
  • Design and calculation of the applied forces on part of the canvas of a auto-adaptive floating frame
  • Systems of sliding perimeter edges and protection systems of the back.
  • Folding auto-adaptive floating frame for the restoration of large format canvases.
  • A moulding frame with a floating auto-adaptive suspension system for recto-verso paintings on canvas.

The tension of the paintings on canvas - practical part: (32 hours) 

  • Design and structural analysis of a new frame: the traditional auto-adaptive floating frame
  • Making many types of stretchers with floating auto-adaptive systems.
  • Making of System to carry out a floating auto-adaptive frame.
  • Making of floating systems using external tensors
  • Fitting a canvas with a floating system.

Illustration of case studies and exemplary restorations. (10 hours)

    Learning Achievements (Dublin Descriptors)

    • The student must show the control of basic skills related on identification of performance techniques and constituent materials and the reading of the state of preservation of the painting in relation to its conservation history;
    • The student must show the requisite skills to use theoretical and practical knowledge that enable it to properly design the restoration and / or maintenance project according to actual needs of the work with particular interest in the material and structural aspects, even in the face teaching cases problematic, and to operate with a certain degree of autonomy both in the preliminary phase of the study (design phase) is in the purely operational phase;
    • The student must show the ability to apply the knowledge gained in previous courses and to develop a personal research relating to the concepts assimilated in his studies.
    • The student must show the ability to draw up an accurate technical report of work done with the reasons for such materials and methods chosen, and its digital documentation performed in the different time phases of the intervention.

    Teaching Material

    The teaching material prepared by the lecturer in addition to recommended textbooks (such as for instance slides, lecture notes, exercises, bibliography) and communications from the lecturer specific to the course can be found inside the Moodle platform › blended.uniurb.it

    Supporting Activities

    A set of texts and pictures will be provided as a support for the lectures with notes and technical papers.

      • Graphic documentation;
      • photographic documentation;
      • Card detection and documentation.
    • The work will be completed and corrected during the module course and delivered in electronic form and paper copy, during the exam.
    • Photographic images should be properly numbered and linked to its caption.
  • The examination consists of an interview to be incurred with teachers who belong to the modules followed. The oral exam will focus on:
