ABSTRACT:
This invention is to prevent coloring or clouding of the molded article, and also to prevent fusion between the glass blank and the mold member and crack formation in the molded article.
The glass blank is provided with the surface layer containing a lower content in water-soluble components than in the core part of the glass base, and a hydrocarbon coating layer formed on the layer. The blank is then press molded.
