摘要
Objective of the present invention is to provide a glass melting furnace, a process for modifying a glass melt and a process for producing glass melt, whereby composition-modified glass melt containing an additive component at a high concentration can be produced with an excellent quality. The glass melting furnace 10 of the present invention is a glass melting furnace 10 for adding an additive to a molten state glass to form composition-modified glass melt, discharging the composition-modified glass melt, and a forehearth 20, said forehearth comprising a feed portion to feed an additive, and a heating means to form a heating gas phase portion above the liquid surface of the glass melt to convert the additive from the feed portion into melted particles of additive below the feed portion.
