S. machine controller (22) by way of which, in a manner dependent on the measured value, a hollow glass article can be identified as being defective and rejected. The arrangement permits automated monitoring of the vacuum operation and a lessening of the burden on operating personnel, and serves for the automated assurance of product quality.

A glass container blank mold includes a mold portion having a neck end, an opposite baffle end, and a molding surface located between the ends that partly defines the shape of an exterior surface of a glass parison formed in the mold. Axial cooling channels formed within the mold portion extend axially alongside the molding surface and radially outboard of the molding surface. Heat block channel locators are formed on one of the ends of the mold portion. Each locator is visibly discernible from the end on which the locator is formed and radially inboard of the cooling channels. Each locator has a thermally insignificant depth and is located such that, when a heat block channel having a thermally significant depth is formed at the locator, heat transfer characteristics of the mold portion are altered between the molding surface and at least one of the cooling channels.
