A method of preparing molten glass in a melting tank of the continuous type by utilizing, as part of the ingredients, waste glass which may be either pulverized cullet of chopped glass fiber and may comprise an organic substance detrimental to the color or other properties of the molten glass. The waste glass and other raw materials are fed to molten glass in the tank continuously but separately such that the waste glass is remelted without contacting the unmelted raw materials and that remelting of the waste glass is preceded by burning of any organic substance possibly adhered to the waste glass fed to the tank and dissipation of the resultant combustion gas.

A method of preparing molten glass in a melting tank of the continuous type, comprising the steps of: continuously feeding a mixture of powdered raw materials of glass to molten glass present in a melting zone of the tank; continuously feeding waste glass, which may comprise an organic substance detrimental to the color or other properties of the molten glass to be prepared, to said molten glass in said melting zone separately from the feeding of said raw materials such that the waste glass fed into said melting zone undergoes remelting without contacting the raw materials fed into said melting zone and yet unmelted; and burning any organic substance comprised in the waste glass fed into said melting zone by maintaining a high temperature oxidizing atmosphere in a region of said melting zone where the waste glass is fed into said melting zone and dissipating a resultant combustion gas before remelting of the waste glass fed into the melting zone.
