|Course||Resin Yellowing and Removability: A Practical Review of All the Data|
|Institution||Canadian Conservation Institute|
This seminar will provide a review of the applied scientific data relevant to the yellowing and removal of aged resins using organic solvents.
Yellowing and removability data of old and new resins will be reviewed, two- and three-dimensional solubility systems examined, and participants guided in the use of solubility charts. One-dimensional approximations and their shortfalls will be addressed, and the role of evaporation, capillarity dissolution, and swelling discussed. Varnish resins, drying oils, pigments, adhesives, and aging processes will be reviewed in-depth.
Upon completion of this seminar, participants will be able to:
Practicing conservators who want to refresh their knowledge of the stability of resins used in conservation, especially those used as varnishes
Note: This seminar presumes familiarity with the issues, the common techniques, and graphical presentation of data.
