    Abstract: Plurality of granules comprising a ceramic core having an outer surface and a shell on and surrounding the core, wherein the core comprises first ceramic particles bound together with a first inorganic binder, wherein the first inorganic binder comprises reaction product of at least alkali silicate and hardener, wherein the shell comprises at least a first concentric layer, wherein the first layer comprises a second inorganic binder and optionally second ceramic particles, wherein if present the second ceramic particles are bound together with the second inorganic binder, wherein the second inorganic binder comprises reaction product of at least alkali silicate and hardener, wherein for a given granule, the first ceramic particles are present in a first weight percent with respect to the total weight of the core and the second ceramic particles, if present in the first layer of the same granule are in a second weight percent with respect to the total weight of the first layer, wherein for a given granule, the first weight percent is greater than the second weight percent, and wherein the granules have a minimum Total Solar Reflectance of at least 0.7. The granules are useful, for example, as roofing granules.
