Public Lecture

Conservation of Tracing Paper


Content : There are three major groups of tracing papers : impregnated papers, papers exposed to acid and papers which are made from over beaten fibre pulp. Each manufacturing process influences the dimensional stability of these papers.

The purpose of the course is to understand the material properties of tracing paper and how these affect conservation decisions and treatments. Participants will learn different treatment techniques adequate for tracing papers.

The main focus of the workshop is to gain an understanding of several treatment techniques through hand-on working on original and dummies.
