Abstract
A glass container that includes a microwave susceptor coating on an exterior surface thereof, and a process for healing flaws in an exterior portion of the glass container. When the glass container is exposed to microwave radiation, the microwave susceptor coating generates heat and selectively and locally provides a major portion of such heat to regions of glass in the exterior portion of the glass container that are in close proximity to the flaws. These regions of glass in the exterior portion of the glass container may be selectively and locally heated so that the glass therein can flow and thereby fill-in the flaws in the exterior portion of the glass container. This process can be used to heal flaws in an exterior portion of a glass container without impairing the structural integrity of the glass container.
