A method of manufacturing a glass container includes melting a batch material, which contains cullet, to produce molten glass having a soda-lime-silica chemical composition. A flow of molten glass is delivered to a forehearth and conditioned within the forehearth, which includes reducing a temperature of the flow of molten glass such that the temperature of the flow of molten glass at an outlet of the forehearth is less than the temperature of the flow of molten glass at an inlet of the forehearth. Additionally, the method involves introducing colored cullet into the flow of molten glass, which produces colored striations within the glass flow. An output of conditioned molten glass is discharged from the forehearth and a glass container is formed from the conditioned molten glass. The glass container has a glass substrate that includes random streaks of color.
