Abstract

A multilayer glass structure constructed by joining the edge portions of a plurality of glass sheets by a sealant through spacers having an adsorbent filled therein. According to this invention, the adsorbent comprises a combination of a granular zeolite composed of a core of a synthetic zeolite/clay binder mixture containing the synthetic zeolite in an amount larger than its average content in the granular zeolite and a shell of a synthetic zeolite/clay binder mixture containing the clay in an amount larger than its average content in the granular zeolite, with granular activated carbon having on its surface 1 to 20% by weight, based on the activated carbon, of a coating of a synthetic resin latex. The adsorbent can effectively adsorb water vapor and the vapor of an organic solvent evaporated from the sealant, and prevent dew deposition on the glass surface. Moreover, it does not yield dust even when the glass structure is handled under severe conditions.
