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 work is a response to the needing of the Schwab Museum in Biel. This institution presents an exhibition of archaeological objects. This project will take part of a bigger plan and go to other museums in Switzerland and in other countries. The transport of this entire exhibition must have a prepared reflexion about his packaging, his transport logistic and about all the informations which...

Non-separable iron/wood composite artifacts recovered from a marine environment are complex objects and require a good knowledge of conservation issues related to both materials before planning treatments. Their conservation involves compromises but intends to first treat the most fragile component while preventing alteration of the associated materials. A particular issue for such treatments is...

The presence of biocides in the process of protecting natural history collections from pest attacks can lead to health problems and can also have effects on the materials of specimen. This essay attempts to study the influence of pesticides on the conservation of naturalia, which are made of composite organic materials. This mainly includes vertebrates, insects, herbarium collections and specimen...

Nous avons pu au cours de notre formation nous apercevoir que la majorité´e des produits organiques présents sur les artefacts ethnographiques (patines, liants de polychromie, etc.) est généralement insuffisamment étudiée, peu documentée et rarement analysée. De ce fait, le conservateur-restaurateur qui souhaite connaître la nature d’un liant que se soit pour la documentation d’un...

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...
