We study the drying of charged colloidal dispersions in droplets confined between two circular plates. More precisely, we combined this technique with in-situ measurements of concentration fields using Raman micro-spectroscopy, of flow patterns using particle tracking, and of drying-induced mechanical stresses using a precision scale, to probe the roles of (i) colloidal interactions, (ii) buoyancy-driven flows, and (iii) the liquid to solid transition, on the dynamics of drying.
