ABSTRACT:
A method of consolidating fine pores of a porous glass by impregnating the fine pores with an energy decomposable compound exemplified by SiH.sub.4. Energy is applied to the decomposable compound thereby forming active species which bond with each other and the functional groups on the surface of the fine pores three-dimensionally to thus form a glass network structure in the pores.
