Abstract:
Specimens of new and archaeological leather before
and after restoration were investigated. It was determined that both the
ageing of leather and its further restoration affect the amount of
polar amino acids in the leather. TG, DTG and DTA studies of the new and
archaeological leather before and after restoration allowed a conclusion
to be drawn that the prevailing process in the thermal destruction of
the new leather is the breakage of cross-linking formed in tanning. In
its turn, the prevailing process in the thermal destruction of the
restored leather is oxidation of the products of reaction between
collagen and organic substances introduced during the restoration.
