Popis:	Glass microspheres were treated with purified water to observe the formation of capillary bridges between the contacting microspheres using high resolution environmental scanning electron microscopy. The observed bridges between glass microspheres were found to shrink under exposure to the electron beam showing evidence of the gelatinous nature while identical experiments with gold spheres did not show any connecting bridges. It was found that the bridges between glass microspheres consist of siliceous corrosion products with high Na concentration which alter interfacial behaviors of contacting glass colloids.
