Course Enrolment Limitations

The course is also offered to the students of the fields other than those the course is directly associated with.

fields of study / plans the course is directly associated with

• Chemistry of Conservation - Restoration (programme PřF, B-CH)

Course objectives

The course is oriented to chemistry and methods used for conservation-restoration of objects that were made from organic materials, such as paper, wood, leather and textile. Students gain a survey about chemical agents and methods used in this field of care of cultural heritage.
