Technical Study and Conservation - Treatment of a Horse Model by Dr Auzoux

Abstract

This paper reports on technical investigations and conservation work carried out on a papier mâché anatomical model of a horse created in the mid-nineteenth century by Dr Auzoux. The object suffered from a structural unbalance due to the distortion of the internal metal structure, and its painted surface exhibited severe flaking. The treatments mainly entailed surface cleaning and consolidation of the paint layers. A gelatine with a good adhesive power and a high gel strength was chosen as a consolidant. The method developed proved very effective and could be applied in the future on other deteriorated Auzoux models. In order to better understand the flaking process, mock-ups of painted surfaces were prepared and were artificially aged under cycling heat and humidity. This experimental work showed the importance of maintaining optimal and stable climatic conditions for the storage of the model. A scientific examination of the techniques and materials involved in the fabrication of the horse was conducted using historic sources as well as analytical investigation. The findings confirmed previous data published on Auzoux models. It also unveiled further information not reported to date as this type of research on such a large Auzoux model had never been carried out before.
