| Abstract: | This diploma thesis examines the sales counter of the former lingerie shop, Rositta, which was designed by Karl Schwanzer in 1951. In 2018 it was donated to the Vienna Museum together with the Karl Schwanzer estate. Originally, according to Schwarzer’s concept, the object had a wood surface with a transparent varnish. During the course of the shop’s redesign in the late 1960s, the sales counter was painted grey. The focus of this thesis is to determine whether it is possible and desirable to remove the grey paint while at the same time preserving the historic surface coating. As part of the diploma, a comprehensive analytical examination of the object was carried out. This made it possible to identify the historic clear varnish, which consists of a predominantly shellac coating, and that the grey reworking was an alkyd resin coating of four layers. After test to remove the top coat using solvent gels and mechanical methods, the alkyd resin was successfully separated from the shellac coating using laser irradiation, which was carried out on test areas on the object. |
