"The Mosaic of Last Judgement from St. Vitus Cathedral in Prague is a medieval masterpiece created in late 14th century by Venetian craftsmen. If very dramatic history and various problems encountered are taken into consideration, the current state of preservation is acceptable, perhaps mainly due to systematic effort to protect the valuable item of cultural heritage. The research project, part of which is presented here, also aims on developing effective means for preservation of the precious object. It concentrates on finding formula for creation of protective layer that eliminates influence of chemicals present in air and in water, while being stable itself. The main goal of the investigation is to help in finding the best formula for protective layer that is most stable itself, i.e. which does not represent a future obstacle in viewing the mosaic, e.g. because of losing its transparency." .
