Abstract
A graphite funnel inserted into a metal funnel support sleeve guides hot glass gobs from a furnace to the glass blowing mold. The graphite insert is adjustable by set screws and is easily repositioned. The graphite insert has an outer diameter slightly less than the metal retainer to allow ambient air to pass upwardly past it.
