摘要：A strong, light-weight foamed weight bearing structural member havinginsulating properties and withstanding atmospheric erosion is formed by introducing aplurality of hollow bodies with shells thereabout into a molten mass of refractorymaterial as a foaming agent and freezing the hollow bodies in place. These shells providecolor, strength and texture characteristics to the structural member and may be steerednon- uniformly such as near the outer surface to provide toughness, texture, or color,preferably by electrically charging the bodies and establishing an electric field in themolten mass of refractory material.
