Zusammenfassung:PURPOSE:To produce a relatively large spherical glass body without limitation in glass composition by putting a molded glass in a solution of hydrofluoric acid and/or water accommodated in a rotating cylindrical tank. CONSTITUTION:A molded glass having 1 to 200mm diameter is put in a cylindrical tank accommodating a solution of hydrofluoric acid and/or water while the cylindrical tank is rotated. The sharp surface of glass is dissolved in the solution of hydrofluoric acid and/or water thereby so as to make the molded glass spherical.
