A method of blow molding glass containers, comprising:

blow molding a first glass container with a first lower portion configuration using a common mold body and a first interchangeable mold bottom plate corresponding to the first lower portion configuration of the first glass container;
and
blow molding a second glass container with a second lower portion configuration different from the first lower portion configuration and using the common mold body and a second interchangeable mold bottom plate different from the first interchangeable mold bottom plate and corresponding to the second lower portion configuration of the second glass container.

A glass container blow mold, comprising:

a mold body establishing a mold body cavity and including a circumferentially extending body outer wall having a lower mating surface;
and
an interchangeable mold bottom plate establishing a bottom plate cavity having a first configuration and including:
a circumferentially extending wall circumscribing a longitudinal central axis,
a mold mating wall extending axially and radially outwardly from the circumferentially extending wall and having an upper mating surface that mates with the lower mating surface of the mold body and also having an interior surface that extends axially and radially inwardly, and
an axial end wall extending axially and radially inwardly from the circumferentially extending wall across the longitudinal central axis and having an interior surface that includes a punt uppermost surface and wherein the axial end wall extends axially inwardly and radially outwardly from the punt uppermost surface toward the interior surface of the mold mating wall.
