Summary:An all-electric glass-melting deep furnace and a method of refining and supplying glass are disclosed in which high-quality molten glass is efficiently produced in large quantity at high heat efficiency. The glass-melting deep furnace 20 has a bottom 2 and a side wall 4 constructed by piling up fireproof bricks 3 on the perimeter of the bottom 2 . A height H of the side wall 4 is set to be twice or more than twice as long as an inside dimension D of the bottom 2 of the furnace. Since the furnace 20 is deep, there can be achieved a thick batch layer, a space in which glass is melted at high temperature, and a cooling area which is necessary to refine molten glass. The furnace makes it possible for the molten glass 6 to absorb fine seeds by its pressure and cooling effects that are produced when the seeds move downward to the bottom 2.
