Study of Materials and Techniques for the Conservation of Two Miniature Paintings

Abstract


This research includes a study on the conservation of two miniature paintings produced by unknown artists and probably dated to the second half of the 18th century. These paintings are registered at the Museum of Helwan University, Faculty of Applied Arts, Giza, Egypt, No. (A) of 100/6.

This research also includes a historical and artistic study of the paintings. To study the materials and techniques used in their execution, several methods were used. XRD, XRD-EDAX was used for the examination and analysis of inorganic materials; in the case of organic materials, FTIR, UV was used to identify the pigment materials, glue, varnish, isolation layer or condition of the paper support. The oil medium in the paint layer was identified by the GLC method. Cross sections of both paintings were examined to find out about the technical knowledge used in constructing the painting / pictorial layers.

Finally, this research involves a study of how to separate two oil paintings executed on one paper support, and the most important procedures needed to carry out this step, as well as those necessary for reconstructing the painting layers. In addition, a new method is described to treat cracks.

Another new method was used to protect the paper support of these paintings from high relative humidity. This research also proposes a new tear mending method for paper objects instead of the traditional methods used in international paper and manuscript conservation laboratories.
