Apparatus and method for inspecting hot glass containers by sensing the heat radiation from the bottles. Newly formed glass containers are moved past the apparatus of this invention in a single file immediately after leaving the bottle forming machines. A series of four heat-sensing probes register the heat radiation pattern of containers as they pass by. A logic unit determines if the container is of the proper diameter, standing upright, and has a neck portion that is not significantly inclined from the vertical. Containers which are lying down, two containers stuck together or containers, which have a bent neck portion are rejected.
