  Early sedimentation in a liquid mixture off-critically quenched in its
miscibility gap was investigated with a light attenuation technique. The time
evolution of the droplets distribution is characteristic of an emulsion
coalescing by gravitational collisions. This sedimentation behaviour has given
access to the phase-separating kinetics and a crossover on the way toward
equilibrium was observed, which separates free growth from conserved
order-parameter coarsening with a crossover time fitting well to theoretical
predictions.
