Beschreibung
Zusammenfassung:	The present invention is to provide a molten glass producing apparatus realizing simultaneously the production of a glass article of high quality and save-energy in producing molten glass, a molten glass producing method employing the molten glass producing apparatus and a method for producing a glass article. In the molten glass producing apparatus having a vacuum degassing apparatus, the melting tank is provided with a separating means for separating the area for circulating the molten glass in the melting tank into an upstream circulation flow and a downstream circulation flow, the distance from the separating means to the downstream end of the molten glass flow path in the melting tank is from 0.1 L F to 0.45 L F where L F represents the length of the molten glass flow path in the melting tank, a wide portion is formed in a first conduit structure at a upstream side in the flowing direction of molten glass, the width of the wide portion being larger than another area of the conduit structure and means for cooling the molten glass passing through the wide portion is disposed in the wide portion.
