Glass shaping method and glass shaped article formed by the method

A glass shaping method, comprising:

• a mold forming step of forming a mold having a concavity by use of a base material which does not deform at a higher temperature than a softening point of glass;
• a glass molding step of heating a glass substrate at a temperature equal to or higher than the softening point of glass, sealing softened glass or molten glass into the concavity of the mold, and cooling and solidifying the softened glass or molten glass to mold the glass substrate;
• a glass processing step of performing machining, such as grinding and/or polishing, of the glass substrate together with the mold, or only the glass substrate, with the glass substrate being sealed in the concavity of the mold, to form a glass shaped article;
• and
• a mold elimination step of eliminating the remaining base material of the mold after the glass processing step to remove the glass shaped article from the mold.
