Summary:An apparatus is provided for producing thin glass ribbons from molten glass. The apparatus includes a drawing tank, a direct heater, and an indirect heater. The drawing tank has a lower elongated nozzle opening through which the molten glass can exit downwards. The direct heater has one or more heating circuits operable to heat the drawing tank in a first heating zone. The direct heater has a power source for each on the heating circuits. Each heating circuit has connections to connected to a wall of the drawing tank so that current from the power source flows through at least a portion of the wall and heats the wall. Each heating circuit also includes current-carrying portions of the wall. The indirect heater has one or more heating elements to heat the drawing tank in a second heating zone.
