3D Digitisation plays a crucial role in the conservation of objects - especially sensitive glass objects such as the glass models of marine invertebrates in the Zoological Collection of the University of Vienna, which were created by Leopold and Rudolf Blaschka in the late 1880s. Glass is a fragile material that can easily be damaged by external influences. This makes it difficult or even impossible to exhibit glass objects permanently or even temporarily. 3D-Digitisation (photogrammetry and high-resolution 360° photography) is a valuable method for both: conserving delicate glass objects and making them more accessible. By using 3D digital copies, the risk of physical damage to the original objects is minimised. At the same time, digitisation enables a deeper analysis, documentation and interaction with these valuable cultural objects. The lecture presents the importance of 3D digitisation as a strategy for the documentation and presentation of highly sensitive objects using the example of the Blaschka models, as well as the aspect of archiving and visualisation of the digital files.
