Give students the necessary tools to face the design of a restoration project, able to work on an artwork on canvas from the structural point of view, being able to operate in the cleaning of polychrome works with the use of new generation emulsions and microemulsions and finally give the necessary tools to know how to handle the new technologies in the field of restoration.
Analysis of the rheological behavior of the constituent materials: 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 (6 hours).
Consolidation of paint layers and support: traditional and synthetic materials and use of the vacuum, including the design and implementation of a system for the vacuum. (16 hours)
Application of inserts and compensation of discontinuity and processing of cutting and tearing by the use of the microscope and load tests at break (16 hours).
Remove the lining, strip lining and use of Beva in the lining (8 hours).
The concept of minimal intervention and the concept of not lining where possible (2 hours).
The tension of the paintings on canvas - theoretical part: 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. Measures to give uniformity to the forces applied to the painted textile.
Models and mechanisms for self-expansion frames and frames floating self adaptive. Low impact solutions for the reuse of the original frames. Recovery of ancient frames and study of reticular frames. 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: Design and structural analysis of a new frame. Structural calculation of the sections of the materials that make up the frame. System to carry out a floating auto-adaptive frame. Lien Test of a canvas on a frame giving uniformity of distribution of the weight. Operations to keep the original frame by transforming the lien by inflexible to floating. Fitting a canvas with a floating system.
Design and calculation of the overstrain of tension. Illustration of case studies and exemplary restorations. Applications on models and / or real artifacts through sample models.
(41 hours total of theory and practice on the tension of the paintings on canvas)
Treatments for cleaning works on canvas: a depht into the emulsions and micro emulsions for cleaning polychrome, new generation silicone polymers, preparation of kits and systematic use of the test for cleaning (12 hours).
Method of control over the material, before during and after the restoration with the help of new technologies: photography, working methodology, monitoring, documentation and practical realization of sereval methods of image capture, theirs analysis including post-production (24 hours).
It's requested the frequency to previous models
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.
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
It will be provided a dossier of texts and images by lecture notes and technical articles.
Didactics, Attendance, Course Books and Assessment
The teaching of the course will be based on technical and theoretical lessons and practical demonstrations by the teacher and in a practical part on the works carried out in the laboratory samples or directly by students

The examination consists in:
1) To take the exam, the student must submit a technical report of the operations project and/or restoration works phases made in the laboratory, drawn in a group or individually.
The report will be developed according to the model provided by the teacher during the modules and it will include:
- 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.

- Operations carried out in the laboratory
Bibliography provided by the teachers.
