The use of mucilage extracted from opuntia ficus indica as a color fixative on historical materials

This paper will present the results concerning the use of new material as a consolidant and/or colour protector. A specifi c polysaccharide material extracted from the prickly pear (Opuntia fi cus indica) has been tested on modern papers and historical materials. An ancient book (18th-19th century) was chosen as historical material. Before applying the polysaccharide material, a conservationrestoration preliminary treatment was carried out on the book’s pages: sampling, fi bre analysis, dry cleaning, ink solubility, pH test, thickness measurement, and wet cleaning. The polysaccharide material was then applied with different techniques, and the treated sheets were analysed by FTIR- ATR. In the second part of our work, we decided to use the mucilage extracted from Opuntia Ficus Indica to test its use as a colour fi xative. Thus, the procedure involves removing impurities with wet cleaning, with the sample wholly immersed in water. This cleaning is the best method for removing contaminants from the paper or fabric backing, it can be used on paper or objects painted in watercolour. The material was applied in different ways (with extraction in alcohol and solid form by means of a spraydryer in various percentages with sericin), and a physico- chemical characterization was carried out by FTIR- ATR and SEM analyses. The results gave excellent evidence of the protection of colours sensitive to aqueous treatments. Therefore, applying this material can be suggested as a new cleaning method for water- soluble materials.
