A livery coat, worn by a servant in the household of Prince Klemens von Metternich of Austria (1773-1859), was used as a case study in the analysis and identification of original and non-original construction methods and materials. The coat, made from a fulled wool, a plain weave wool, decorative silk braid and metal buttons, was tested and prepared for dry-cleaning within the textile lab of Winterthur Museum. The three-dimensional shape of the coat and the individual elements (the braid and buttons) were protected and supported by generous amounts of nylon netting secured with a cotton thread. Perchloroethylene (C2Cl4), currently the standard solvent within the dry-cleaning industry, was used in a manually controlled dry-to-dry unit. A 0.5% charge of a commercial non-ionic surfactant was added to remove unoxidized water-soluble soils.
