Abstract: There is provided hollow microspheres comprising: at least 45 wt % of recycled glass based on the total weight of a feed composition from which the hollow microspheres are derived, wherein the hollow microspheres have a density of less than 1.25 g/cm3, strength at 20% volume reduction greater than 20 MPa and have a substantially single cell structure. There is also provided hollow microspheres comprising: a blend of recycled glass and glass feed, wherein the hollow microspheres have a density of less than 1.25 g/cm3 and are made from a feed composition that is essentially free of an added effective blowing agent. There is provided a method for making hollow microspheres.
