Abstract: When finely divided SHIRASU (pumice ejected from volcanoes and the secondary deposit of such pumice) is roasted at a temperature in the range of from about 800* to about 1200*C, the vitreous particles contained in said SHIRASU foam and consequently produce light-weight hollow glass microspheres. The hollow glass microspheres so produced are superior to conventional glass microspheres especially in their resistance to heat and can therefore be combined with metal, carbon, as well as with cement and other materials to produce novel lightweight composites.
