In many old dioramas, material mysteries abound. As a Curatorial Assistant at Tullie House, I’ve encountered a tree trunk made from a Robinson’s fruit juice box, a fake roof that contained fibrous signs of asbestos, and a hodgepodge of unidentifiable paints and old plastics. The museum’s new-in-post Biodiversity Curator discovered pests thriving amongst the real vegetation and a 30-year-old slice of bread in a garden scene.

Dioramas aim to create the illusion of real habitats for their taxidermy inhabitants, and they use a huge range of materials to do so. After decades of neglect and destruction there is now wider recognition that habitat dioramas can instil a sense of wonder in visitors that no amount of digital wizardry can replace. Through my dissertation research for an MA in Preventive Conservation at Northumbria University, I wanted to find out more about what materials have been used in dioramas over time, how these might impact the preservation of specimens, and what we can do to better protect the dioramas that remain. I put a call out to ask, ‘What’s in your dioramas?’ through an online survey and received 30 responses from people with experience in a range of different sized institutions and private practice.
