ABSTRACT:
A glass body having a fluorescent pattern inwardly of a surface thereof is formed by depositing a first material in a predetermined pattern on a surface of glass containing readily ion-exchangeable first ions, the first material containing second ions capable of ion-exchange with the first ions, one of the glass and the first material containing ions for providing a fluorescence center, and by causing the second ions to penetrate into the glass through ion-exchange with the first ions so that the fluorescence-center providing ions may be distributed in a pattern which is in positive or negative relationship with the predetermined pattern.
