In the Central European context the imitation of natural stone is called stucco marble or scagliola. During its manufacture,
the mixture of gypsum, animal glue and pigments produces a marble-like structure and after several sanding and polishing processes
attains a glossy surface.
Scagliola plays a significant role in the history of interior design in the 18th and 19th centuries in Central Europe. Originally,
it was used during the first half of the 17th century as imitation of stone inlaid work, pietra dura, for table tops and as
antependia. Scagliola interiors in the 18th century the main phase of use show individual designs, colours and shapes. This
technique substituted stone because coloured marble was expensive and types of natural stone have a limited colour range.
In the first half of the 19th century, scagliola found little or no application but was rediscovered in the century´s second
half. In Vienna, high-quality stucco marble was used extensively in public buildings or private palaces.
Recent research focuses on the interior of churches during Baroque and Rococo in southern Germany. Studies on conservation
methods of scagliola hardly exist at an international level. In order to ensure the preservation of these valuable surfaces,
a catalogue is being compiled of scagliola works in the 19th century in Vienna as well as an overview on actual conservation
