The father and son team of Leopold and Rudolph Blaschka created meticulous and incredible glass models of sea creatures and floral specimens in the second half of the nineteenth-century. Examples of their work can be seen in a number of museums, including the Natural History Museum in London and the Corning Museum of Glass, which produced this short video on an exhibition of Blaschka Glass models.
The fragility of these models is understandably a concern to curators. A video produced by the Natural History Museum in London discusses these concerns and described the process by which 3-D scans were made of some of the models as a way to understand and preserve them.
The glass models are a compelling combination of art and science, and a wonderful example of the complexities of curating such objects.
