In this paper, sessile drop experiments were made in the copper-silver system at the eutectic temperature and 900°C. Wetting, or acute contact angles, were observed for specimens in chemical thermodynamic equilibrium. Spreading occurred when the substrate was not in chemical equilibrium with the liquid. Finally, the interface does not remain aligned with the free surface of the substrate only in the presence of reactions.
