As the fined glass melt exits the furnace through the throat, it enters the conditioning area. For many glass products such as containers, glassware, or glass wool, thermal conditioning is achieved in the forehearth. The goal of the forehearth is to deliver a homogeneous glass at the right temperature to the outlet. Forehearths can also be used to produce colored glass by mixing frits directly into the melt. The glass delivery must be well-controlled in stable operati on, before and aft er a job change.

This course gives an overview of the different parameters that can be used to control a feeder in an optimal way.
