The production of all types of tracing paper is based on two main methods: 1) paper fibre or wet pulp is beaten to break and shrink the fibres and thus reduce the porosity and increase the transparency of paper, 2) already produced paper is coated or filled with a particular material that makes the paper transparent. The following types of tracing paper are known: • Parchment imitation – wood pulp is beaten for a long time, giving the end product transparency and resistance to water and dirt. • Parchment paper (vegetable parch- ment) – is a type of paper, for which sul- furic acid or zinc chloride is used during its production. • Oiled paper – paper is soaked in flax- Fig. 1.

Prevailing pH values in tracing paper are close to neutral. This shows that in many cases, from the chemical point of view, pa- per is rather stable. Mechanical damage is the main problem. It is defined that in the production pro- cess of tracing paper, starch was used as a sizing material. For impregnation coating, various oils, turpentine, and damara resin were used; in the case of document LMAVB RS F320-1726, wax might have been used. Information achieved in the course of the investigation about the composition of tracing paper documents and materials for copying aids the restorers in learning more about the objects, and in choosing suitable methods and materials for conservation and restoration. The results of the analysis are presented in the table 1.
