Photographs of the samples containing material composition C4 with (from left to right) S = 0.65, S = 0.8, S = 0.9, S = 0.95 and S = 1. These photographs were taken more than nine months after sample preparation. Three distinct layers are visible for the samples with added secondary fluid. The top layer contains Pickering-stabilized emulsion droplets as shown in the magnified inset. The middle layer contains pure aqueous glycerol and the bottom layer is formed by the unstabilized, settled particles. The sample with S = 1 shows only two layers (aqueous glycerol over settled particles).
