Photoelastic samples can also be casted from more common materials than [urethane](https://git-xen.lmgc.univ-montp2.fr/PhotoElasticity/Main/wikis/molding-urethane). For example gelatine is a very good photoelastic material [picture]
The different photoelastic gels
-------------------------------
Gelatine 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)]
