Summary Description

The SUPSI sample collection consists of about 600 material samples (wall paintings, mortar, plaster, stucco and stone) collected from immovable heritage sites in Switzerland and from other countries covering historical periods from about 300 BC to 1990 AD. The samples have been collected by SUPSI researchers during several research projects and professional assignments. Sampling is still on going and new samples are added to the collection every year. The samples are used for research and educational purposes in SUPSI conservation courses. The catalogue of the SUPSI samples collection is currently being reorganised and will be available online by the end of the year.

Most samples are well documented with information regarding location, sample description and results of the analysis performed. Therefore, the collection potentially has great value for scientific, historical, artistic and educational research.
