Ornamental features are added to glass by heating a small area of the glass which causes the glass to soften. A stamp having a raised or recessed surface is then pressed against the soft glass to form an ornamental feature on the surface. The unheated glass remains cool and is hard to provide structural support to the glass as the stamp is pressed against the surface. The stamp is then removed and the heated glass with the ornamental feature is allowed to cool and harden.
