Abstract
A process and an apparatus for imparting coloration to a glass container having a strikable glass container composition. One or more portions of the glass container are selectively and locally exposed to a temperature at or above a glass container striking temperature to affect a color change in the one or more portions of the glass container. The coloration process may be carried out by passing the glass container through an interior of an apparatus having a heating system configured to locally heat a first region within the interior to a temperature at or above a glass container striking temperature and a cooling system to locally cool a second region within the interior to a temperature below the glass container striking temperature.
