The platinum feeding system has started out as a drain system targeting a very directcontrol of the glass temperature from the glass bath to the tip. It has successfully evolved into a segmented and highly specialized feeding system which provides optimum conditions for a controlled glass flow from the bottom of a forehearth to allow a stable furnace pull control as an additional glass consumer providing glass nuggets for in process cullet recycling strategies or to allow to remove circonia-enriched glass which accumulates on the bottom of the forehearth before the glass enters into the feeder; most importantly it is a very versatile system for feeding speciality glass for micro particles like beads, flakes, nuggets etc.
