HEAT AND LOW PRESSURE SUCTION TABLE WORKSHOP
Three Days, October 6th - 8th 2023
Hands-On Practical Workshop
For Professional Paintings Conservators
Conducted by Special Guest Conservators from Milan, Italy
Laura Menegotto and Davide Riggiardi (in attendance)
Leonardo Borgioli (online)
This professional course has been developed around the treatment possibilities of using the heat and low pressure table. The characteristics and methods of using adhesives will be examined, as well as the potential uses of the heat and low pressure table and the principles governing its operation. A theoretical introduction will be followed by application examples.
Objectives
The course aims to illustrate how the heat and low pressure table is effective in solving adhesive, cohesive, and deformation problems on polychrome textile substrates, as well as to carry out total or perimeter cold or heat lining operations. This tool offers the possibility of applying constant and simultaneous temperature and pressure over the entire surface of the artwork, managing to modulate and control the parameters throughout the entire process application.
Location
The workshop will be held at
ACdR Conservation ~ Art Conservation de Rigueur
San Francisco, California
