Researchers have successfully digitized 19th century glass models of 15 marine invertebrates made by Rudolf and Leopold Blaschka. In order to capture the complexity, detail and shiny surfaces of these models, the researchers took 250 to 700 images of each invertebrate, created specific lighting and, for the most difficult models, administered X-ray computed tomography (CT) scans. . . The full team includes Hanken and MCZ Assistant Curator Jonathan Woodward, along with Peter Fried (NYU Tandon School of Engineering), David Brown (Herbert F. Johnson Museum of Art, Cornell University), and Drew Harvell (Cornell University).

“Handling the Blaschka models requires concentration and patience, but it’s a real pleasure to pay close attention to such beautiful and intricate objects,” said Woodward, who performed the micro-CT scans. “I am especially pleased to have contributed to a process that will share these unique objects more widely and more faithfully than ever before.”

“The technique we have developed for combining CT scans and photogrammetry is generic, in that it can work, in principle, for any complex, highly reflective glass sample. It should be interesting and useful to all kinds of museums,” Hanken said. “We would love nothing more than other institutions to use our technique to reveal the beauty and complexity of their objects, as well as ours.”
