PROBLEM TO BE SOLVED: To provide an apparatus and a method which can correctly control the discharge of water from a spray nozzle upon quenching a hot glass sheet. SOLUTION: The spray nozzle is located in proximity to the glass sheet, creating gas in liquid used to quench the glass located in the nozzle. The gas is removed from the quenching liquid. Then, the spray nozzle is used to spray the quenching liquid onto the sheet at a scoring position. The spray nozzle (purge nozzle) has a purge opening and tubing leading to a discharge location. The purge nozzle can have a sloped passageway that pre-stages gas bubbles near the purge opening in the nozzle. The spray nozzle can include a cooling coil passing around the nozzle passageway that enables a coolant to travel along the coil. This cools the quenching liquid passing through the nozzle, and increases the solubility of bubbles in the quenching liquid in the nozzle. A gas filter can receive gas-rich quenching liquid from the pressurized quenching liquid source, remove gas from the liquid, and send gas-depleted quenching liquid to the spray nozzle.
