Abstract: The contribution presents the application of proton induced X-ray emission (PIXE), as a non-destructive analytical method, to the identification and study of historic paper, parchment and textile objects. The results show the possibilities for identification of inks, pigments, dyes, surface layers and inorganic impurities in historic objects made of organic materials. The measurement of elemental concentrations in these materials provides a sound basis for investigation of their composition and of degradation processes. PIXE has been found useful in evaluating the viability of a range of potential conservation treatments by measuring the elemental changes before and after the process has been carried out. Like any other form of analysis, the PIXE method has its limitations, but its great strength is in its non-destructiveness, high sensitivity and accuracy in determining composition and concentration distribution over a wide range of chemical elements. For objects made of complex organic materials the information obtained should be interpreted in combination with other analytical methods. [Copyright &y& Elsevier]

This article presents the author's views on the optimization of leafcasting technique. Leafcasting is used for the production of various conservation paper samples of different fibre types and additives, as well as optimising the technique for conservation. Many research concentrated on the influence bleached and unbleached cellulose fibre had on the quality and on the permanence and stability of the resulting paper. Leafcasting technique is advantageous in comparison to manual methods. Leafcasting is faster and provides superior aesthetic quality and homogeneity between the old paper and the new fill.
