Deconvolution of optical and strength effects from plastic deformation will enable us to more accurately measure equation of states of target minerals of interest. Particularly interesting are regions of the phase diagram approaching structural transitions, especially at extreme states, where the phase stabilities and instabilities change rapidly. I will discuss how we use phase diagram measurements to help constrain equation of states and progress toward quantifying our uncertainties in their construction.
