Glass shaping mold
 A glass shaping mold includes a female mold member having a shaping surface, a male mold member having a shaping surface complementary to the shaping surface of the female mold member, and a felt sheet disposed on each of the shaping surfaces. The female and male mold members are movable toward each other to shape a heat-softened glass object between the felt sheets on the shaping surfaces.
