The precious jewels collection of Ulrike von Levetzow was thoroughly studied and restored. The collection consists of a multi-row necklace, paired bracelets, a ring, two earrings and a belt buckle stored in an original etui. Besides the high quality of manufacturing of all pieces, the main value consists in used materials. The collection was made o...

In this study we used an analytical approach based on complementary techniques that targets all structural levels of collagen in leather to investigate how vegetable-tanned leather deteriorates during soil burial tests. For the first time, a group of deterioration markers specific to molecular, fibrillar and fibrous structure of collagen in leather...

Leather objects, found in archaeological excavations, survive in a specific environment. This leather material is very delicate and only little is known about the mechanism of its (bio)degradation in a soil environment. The main goal of this study was to clarify how leather is affected by a soil environment and why archaeological leathers have thei...

In this study we used an analytical approach based on complementary techniques that targets all structural levels of collagen to investigate the effects of burrial tests on vegetable-tanned lather. For the first time, a group of deterioration markers specific to molecular, fibrillar and and fibrous structure of collagen in leather was associated wi...

Many objects of culture heritage, comprised of leather, need to receive the right treatment to be restored and to elongate their lifespan. Determination of the degradation degree and even better the type of the degradation is a crucial knowledge for the way of subsequent conservation, exhibition and long-term storage. Collagen based materials are v...
