Abstract: The Ishrat Khana mausoleum was constructed in 1464 and is today a ruined protected monument. Badly damaged by two earthquakes and then left to decompose over more than one hundred years, the Ishrat Khana mausoleum was investigated to create an appropriate conservation concept for the materials and decorating surfaces.
In this study, the historic plasters and stucco applications are analysed in detail by using polarizing microscopy and SEM/EDX of thin sections.
All original materials contain gypsum as a binder, some plaster contain lime in addition. Aggregates are quartz, feldspar, mica, carbonates, and soil fragments, which frequently contain calcite (marl). Different binder/aggregate ratios enable a varied application of this building material in Ishrat Khana. This type of historic gypsum mortar is called Ganch in Central Asia.
