Les adhésifs à photopolymérisation radicalaire employés pour le cpllage structural du verre en conservation-restauration : Etude de la résistance au cisaillement de 4 adhésifs optiques polymérisables aux UV

Gillioz, Sandra

Mémoire de master : Haute Ecole Arc Conservation-Restauration, 2014.

Because their polymerization occurs in a few seconds under UV light, Ultraviolet light curing adhesives (UV adhesives) represent a seductive choice for the bonding of glass in conservation, especially when the fragments cannot be temporarily maintained. This thesis evaluated the suitability in terms of mechanical resistance of UV adhesives for the bonding of glass in conservation. Four UV...

Traitement électrolytique localisé des produits de corrosion du plomb et des alliages plomb étain : Mise en application du pinceau électrolytique, le PLECO

Fontaine, Célia

Mémoire de master : Haute Ecole Arc Conservation-Restauration, 2014.

In museum and archive collections, sometimes feature objects made of lead or lead-tin alloys (PbSn). Kept in environments containing acetic acid vapors, these objects can develop an active corrosion. This manifests itself in the form of as white powdery corrosion products composed of basic lead carbonates and hydroxycarbonates. In the past, various chemical treatments could be used to remove it. ...

Die Lederfunde aus dem Schutthügel des römischen Legionslagers Vindonissa. Untersuchungen zum Konservierungszustand

Lang, Urs

Mémoire de master : Haute Ecole Arc Conservation-Restauration, 2014.

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...

La problématique de la radioactivité dans les objets patrimoniaux : identification, évaluation et gestion

Daval, Marion

Mémoire de master : Haute Ecole Arc Conservation-Restauration, 2012.

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...

Die Nachkonservierung eines mit flüssigmen Nylon (Catalon) konservierten ägyptischen Kallsteinreliefs

Lang, Urs

Mémoire de diplôme HES : Haute Ecole Arc Conservation-Restauration, 2014.

The goal of this work was to find a method to secure the fragile parts of the relief. Furthermore it was important to evaluate an exposition concept which enables the display of the object in the permanent exposition of the Archaeological Institute. First, the overall condition of the object and the necessary intervention steps were evaluated. It was attested that the relief was, mainly due to...

Möglichkeiten des Einsatzes von ätherischen Ölen gegen Pilzwachstum auf Trockenholzobjeckten

Egger, Jana

Mémoire de diplôme HES : Haute Ecole Arc Conservation-Restauration, 2006.

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...

L'emballage et le transport d'une exposition archéologique : Evaluation des besoins fonctionnels

aMarca, Mathias

Mémoire de bachelor : Haute Ecole Arc Conservation-Restauration, 2008.

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...

Testing corrosion inhibitors for the treatment of marine iron/waterlogged wood composite artifacts in polyethylene glycol solutions

Sangouard, Elsa

Mémoire de diplôme HES : Haute Ecole Arc Conservation-Restauration, 2008.

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...
