Compositions and methods for glass composites suitable for tissue augmentation, biomedical, and cosmetic applications are provided. The glass microsphere component of the composites are biologically inert, non-reactive and act as a nearly permanent tissue filler. One embodiment provides a tissue augmentation composite containing an effective amount of solid glass microspheres, hollow glass microspheres, porous wall hollow glass microspheres, or combinations thereof with a suitable biocompatible matrix to serve as a bulking agent when injected into a patient. The compositions can be used for soft or hard tissue augmentation as well as delivery of cargos on demand.

In a method for producing an expanded-glass granular material, starting materials containing glass powder, water glass, at least one blowing agent, and metakaolin, are mixed in order to form a homogeneous slurry. The slurry is granulated to form raw granular-material particles, which are foamed at a baking temperature between 780° C. and 950° C. in order to form expanded-glass granular-material particles. The expanded-glass granular material has a long-term water absorption of less than 25 volume percent when the expanded-glass granular material is exposed to water for a time period of 21 days.

A pre-fractured glass laminate that includes: a glass substrate comprising a thickness, a pair of opposed primary surfaces, a compressive stress region, a central tension (CT) region and a plurality of cracks; a second phase comprising a polymer or a cured resin within the plurality of cracks; a backing layer; and an interlayer disposed between one of the primary surfaces of the substrate and the backing layer. The compressive stress region extends from each of the primary surfaces to a first selected depth in the substrate. Further, the plurality of cracks is located in the CT region.
