Collection managers value the natural corrosion layer that forms on the surface of copper-based heritage objects, whether historical or archaeological. In addition to its colour and pleasing appearance, it accentuates their authenticity and historicity.

Développement de Protocoles d’Analyse des métaux patrimoniaux basés sur la Combinaison d'Outils portables, peu coûteux, peu invasifs et accessibles comme aide au Diagnostic en conservation-restauration

The DRYLU project aims to propose solid lubricants (also called “dry lubricants”) as an alternative to traditional lubricants for the conservation of scientific and technical heritage.

The project objectives are to investigate the degradation mechanisms of lacquered brass and to validate non-invasive and effective cleaning methods, which allow conservators to remove corrosion and preserve the lacquers as much as possible.

The aim of this project is to deepen the knowledge of conservation issues of botanical wet collections (plants in fluid) in order to propose adapted protocol for their correct preservation.

This project focuses on developing controlled, safe and effective electrolytic treatments on heterogeneously tarnished historic silver objects, based on a precise knowledge of the variability of the original appearance of their surface...

The objectives of CANS are to improve the knowledge about cans, to develop treatment methodologies respectful of the material authenticity and cultural values of these composite objects and to propose solutions in terms of preventive conservation.

Concevoir un dispositif informatique de suivi post-sinistre des objets, qui sera activé depuis le démarrage de l’évacuation des objets et documents jusqu’à leur retour après traitement.

The DOA project aims at studying and conserving the human remains and the painted cartonnage case of Ta-sherit-en-Imen (Amun’s little one). The mummy dates to the Third Intermediate Period (1069-664 BC) and was brought to the shores of Lago Majore by the Swiss collector Zaccaria Zanoli at the end of

L’imagerie par transformation de la réflectance avec dôme : un outil non invasif d’identification, de diagnostic et de suivi des objets patrimoniaux

This research, which follows the FLUIDS project, is focused on the conservation of botanical wet collections and includes a systematic study of plant collections in fluid.

The HELIX project aims to exploit chemical uptake processes occurring in microorganisms to develop innovative green and non-invasive cleaning methods.

As a follow-up of the project MICMAC, it focuses on innovative biological methods of extraction for the preservation of waterlogged wood suffering from salt precipitation and acidification.

Un projet d’étude et de conservation-restauration en collaboration avec le Musée d’art et d’Histoire de Neuchâtel (MAHN) qui a été mené par les étudiants de première année de master de la spécialité objets scientifiques, techniques et horlogers.

Conservation of gold-imitating varnishes applied to decorative bronzes from the19th century. Definition of associated cultural values and identification of ancient restorations

The consortium is composed of 18 Partner Institutions located all around Europe. HES-SO (HE-Arc CR) is partner for two early-stage researchers (phD Students) positions.

The problem of discoloration of plants preserved in fluid in botanical collections. This project will allow the UR-Arc CR to develop a research line on this kind of heritage and to elucidate the phenomenon of specimen’s discoloration.

By visually inspecting metal objects, conservation professionals propose a first diagnosis of degradation on the basis of their experience and consultation of specialized literature.
