Abstract

PURPOSE: To increase design varieties and enable this to be inexpensively realized by providing decorative undulations on the front surface of glass.
CONSTITUTION: A glass blank 13 which has beforehand been lapping finished is placed on the top of a lower die 12. Next, the glass blank 13 and dies 11, 12 are heated to the deformation temperature of inorganic glass by the flame 15 of a burner 14 and at the same time the upper die 11 is pressed onto the surface of the glass 13, whereby the decorative convex faced glass having convex faces 10 on the glass front surface 9 is formed.
