A method for compressing gases in a contained volume consisting of hollow glass microspheres is described. The gases are compressed under high pressure and can be easily handled and stored. The gases to be compressed and contained in the microspheres are used as blowing gases to blow the microspheres. The metal vapor deposited coating can be reflective of or transparent to visible light. The hollow glass microspheres can be made to contain a thin transparent or reflective metal coating deposited on the inner wall surface of the microspheres by adding to the blowing gas small dispersed metal particles and/or gases of organo metal compounds and decomposing the organo metal compounds. The hollow glass microspheres can be made in the form of filamented glass microspheres with a thin glass filament connecting adjacent glass microspheres.

Hollow inorganic film forming material microspheres of substantially uniform diameter of 200 to 10,000 microns and of substantially uniform wall thickness of 0.1 to 1,000 microns and having a contained gas pressure above 15 p.s.i.g. at ambient temperature, wherein said microspheres are free of laten

Hollow inorganic film forming material microspheres of substantially uniform diameter of 200 to 10,000 microns and of substantially uniform wall thickness of 0.1 to 1,000 microns and having a contained gas pressure above 15 p.s.i.g. at ambient temperature, wherein said microspheres are free of latent solid or liquid blowing gas materials or gases and the walls of said microspheres are substantially free of holes, relatively thinned wall portions or sections, sealing tips and bubbles.
