The invention discloses a glass re-forming process. The process includes the following steps: 1) cleaning; 2) drying; 3) coating; 4) softening and molding. The process of the invention can effectively inhibit the formation of defects such as crystallization, streaks, and stones in the glass forming process, and can effectively inhibit the unevenness of the vitreous body and the generation of shrinkage lines caused by factors such as uneven heating, thermal expansion and cold contraction. The obtained glass molded product has excellent optical properties and mechanical properties, reaches the expected value of the optical glass element, and avoids the waste of materials caused by the need to remove uneven glass parts by grinding or grinding in the deep processing process. |
