A reversible hydrocolloid impression material that exhibits birefringent characteristics was developed. Tests were performed to establish the stress-optic characteristics of the hydrocolloid for use in photoelastic analysis. Physical characteristics are reported which are relevant to the clinician and dental researcher.
