From: Burial-induced deterioration in leather: a FTIR-ATR, DSC, TG/DTG, MHT and SEM study
DSC curves obtained in open crucibles and nitrogen flow for leather samples before and after the 1-year soil burial: a CH; b CC; c SC and d CaC. The dehydration peak, denaturation peak of the collagen–tannin matrix (showing a maximum at Td1), and denaturation peak of the crystalline fraction (showing a maximum at Td2) are indicated
