Photoelastic samples can also be cast from more common materials than [urethane](https://git-xen.lmgc.univ-montp2.fr/PhotoElasticity/Main/wikis/molding-urethane). For example gelatin is a very good photoelastic material, with a high photoelastic constant, which means a small stress induces a large photoelastic effect (Kuske & Robinson, "Photoelastic Stress Analysis"). Gelatin is most likely the most used photoelastic gel but many others like agar or konjac exist ([Tomlinson and Taylor](https://www.spiedigitallibrary.org/journals/Optical-Engineering/volume-54/issue-8/081208/Photoelastic-materials-and-methods-for-tissue-biomechanics-applications/10.1117/1.OE.54.8.081208.short?SSO=1)).
