The garbage heap of the legionary camp of Vindonissa in the Canton of Aargau is well known for the leather finds it has produced. These leather objects were conserved, starting in 1941, by August Gansser and were mounted on 487 carton frames. By the 50's, he developed different methods of conservation and kept record of his activities in handwritten notebooks. The most commonly employed method...

The present work deals with this delicate and often ignored problem. This work has been realized with the purpose of giving museums protocols of behaviour allowing for an ideal reaction in the presence of radioactive substances and to avoid any incident. The four following questions are treated: · What radioactive objects are potentially found in a museum and how can one identify them? · What...

The aim of this work was to carry out a field study on the appplication of conservation in a state scientific institution (but not a museum) containing a rich scientific heritage. The exercise was organised in such a way that it could be carried out on the site of the Besançon Observatory. The setting up of such a project had to begin with an organisational phase of a special type, since the...

Once archaeological iron artifacts are excavated their protective environment is lost. On exposure to the air the objects can dry out and the earthy as well as the corrosion layers become permeable due to the formation of cracks and fissures. Moisture from the air and oxygen get access to the objects. If chlorides are present in the corrosion layers and metallic iron remains in the artifact,...

The goal of this Diploma work is to examine whether essential oils can inhibit the growth of mould on wooden objects. The activity to inhibit the fungal growth of Cinnamomum zeylanicum, Eugenia caryophyllata, Satureja montana and Origanum vulgare in different ethanol concentrations ranging from 1% to 50% were examined in practical experiments at the laboratory of microbiology at EMPA St.Gallen...

The archaeological excavations directed by the paleometallurgical working group of the international programme entitled Human Populations and Paleoclimatic Evolution in West Africa have brought to light important remains of iron making in the Dogon region. Their research shows that the Dogon plateau was a remarkable centre of iron production from the sixth to the nineteenth century. The reduction...

Laser cleaning has been successfully used on a wide range of materials for over 30 years. Laser cleaning of metals, however, has received relatively little attention within the conservation field during that time. Copper alloy outdoor monuments strongly suffer from the effects of the polluted environment to which they are exposed in all urban and industrial areas in the world and there is a...

This paper aims to carry a survey of the actual practices in the management and conservation of archaeological finds in the cantons of Switzerland and questions the position of preventive conservation in the archaeological process. It puts into perspective a theoretical approach of preventive conservation in archaeology, the point of view and experience of practitioners belonging to the world of...

The diploma thesis treats the volatile binding media cyclododecane and its use in conservation- restoration. The dissertation is based on preceding research and specifically treats the most characteristic property of the product: its ability to sublime. Cyclododecane is an industrial product, which was introduced in conservation-restoration in the middle of the nineteen nineties. This was due to...

The invention of gunpowder in the 14th century make possible the emergence of firearms. The mechanical power used by the arc of Antiquity and the crossbow of the Middle Ages was replaced by the gas produced by the explosion of a flammable powder. The technical improvement of the firing system occupied humans during four centuries. Then, the discovery of the chemical powder permit major...
