Abstract:
Waxes as a component of seals, are recognized in our history as adhesives, for surface coating purposes, modeling or casting materials and also in conservation practice. The waxes with mineral, vegetable and animal origin should be connected to modern methods of analysis, due to their complex composition: long chain hydrocarbons, acids, alcohols, esters. They support many mechanical damages in library and archive collections: cracking, pieces lost by an excessive handling of documents. In this paper the compositional analyses of some wax seals belonging to some paper samples have been achieved by Raman spectroscopy and Fourier transform infrared spectroscopy (FTIR) - for molecular structural information of wax materials, by gas chromatography / mass spectrometry (GC/MS) - for evidence of some compounds resulted from degraded wax seal, and by optical microscopy (OM) and scanning electron microscopy (SEM) - for visualization of the damaging effect on the wax seal. All these analytical investigations have been achieved for wax seals detached from the paper samples recovered from two disaffected pulp and paper factories - Letea and Busteni (Romania) belonging to Romanian industrial patrimony.
