Abstract
A glass container production line and process include a first step of heating a portion of the glass container by delivering microwaves and conveying them to the portion of the glass container. Microwave delivery is carried out at a first power level for a first time interval so as to bring the portion of the glass container from an ambient temperature to an intermediate temperature, and at a further power level, which is lower than the first power level, for a further time interval following the first time interval, so as to bring the portion of the glass container from the intermediate temperature to a first predetermined working temperature.
