Summary:An apparatus and method for making glassware by a press and blow technique wherein the pressed parison is formed in an upright mold construction. The said mold construction utilizes a relatively wide cavity body mold and a relatively narrow opening neck mold, and also an intermediate "transitional" mold which is placed between the neck mold and body mold when the parison is initially formed. The transitional or intermediate mold is opened after the parison has been formed to permit the parison to reheat and stretch before being placed in a blow mold or other final shaping mold where the parison is blown or otherwise expanded to the final size and shape desired for the article of glassware.
