Agar spray: New applications of rigid gel for the treatment of large surfaces

18 - 19 SEPTEMBER 2024
Church of Santa Caterina D'Alessandria
Piazza Bellini, 1
Palermo - Italy
The innovative procedure presented during the workshop will provide participants with new theoretical and practical knowledge on the applicative potential of this helpful gelling agent.
The new method developed by the teacher, thanks to the tool adopted for the application, gives the agar new structural characteristics.
For the first time the treatment becomes feasible, safe and suitable for complex surfaces, extended and varied in nature, obtaining results that are difficult to reach with the methods presently known. The workshop will offer participants know-how and skills to master the application of the "agar spray" technique, applicable to paint, paper, wood, wall and plaster.
Ambra Giordano received her B.A. in Art Conservation from the Academy of Fine Arts and Restoration of Palermo in 2004. followed by an M.A in Art Conservation with a specialization in the conservation of paintings from the University of Palermo in 2012
In 2017 she obtained the Il level International Master in "Biology for the Knowledge and Conservation of Cultural Heritage" at the Roma Tre University in Rome Since 2014 she has collaborated with the Research Laboratory of Biology and Biotechnology for Cultural
Heritage at the University of Palermo, and collaborates with national and international museums and training organizations
Today she is a professor in the Art Conservation Department at the Academy of Fine Arts of Napoli.
