The guide includes an upper plate sized to engage the crucible bottom for attachment thereto, and includes an upper orifice drain therethrough for draining by gravity the melt from the crucible. A lower plate is spaced below the upper plate to define a plenum therebetween, and includes a lower orifice drain therethrough. A downspout extends through the plenum in flow communication between the upper and lower drains, and includes a middle orifice drain. A heater surrounds the downspout for heating the melt drainable therethrough. And, a coolant is circulated through the plenum for cooling the guide.
