Earth Optics Video 4: Uniaxial Minerals

In this video, I go through examples where I find a uniaxial interference figure and using it to determine optic sign. For supplemental questions and resources, please check out my webpage at www.earthopticsmineralogy.com Uniaxial Interference figure image: http://jm-derochette.be/Conoscopy/quartz.htm Michel-Levy Chart: University of Liverpool.
