Methods for producing wet gel and xerogel

Abstract

To provide methods for producing a wet gel and a xerogel, in which variation in gel thickness is little even without highly controlling the levelness of the mold and the gels are less likely to break at the time of gelation or demolding. The method for producing a wet gel comprises, in such a state that a second liquid layer 14 made of a second liquid containing a gel raw material, is present on a first liquid layer 12 made of a first liquid, letting the second liquid layer 14 be gelled. The method for producing a xerogel comprises drying the wet gel thereby produced or a solvent-substituted gel obtainable by subjecting said wet gel to solvent substitution.
