    Abstract: Inorg. silicate materials(glass) which had thermoplastic property similar to the org. polymer plastics, were prepd. Thus, the mixt. composed of SiO2 50-95 mole%, and Na2O and/or K2O 3-25 mole% as oxidizing agent was mixed in the glass with above 55 mole%. The composed glass was hydrated by exposing to the gas phase, having a relative humidity of more than 75%, at>=100≦̸C for 0.25-96 hr. The amount of water contg. on the glass surface was reduced by exposing to make title materials.
