Abstract: According to one embodiment, a method for forming a laminated glass sheet includes forming a multi-layer glass melt (300) from a molten core glass (106) and at least one molten cladding glass (126). The multi-layer glass melt (300) has a width W m , a melt thickness Tm and a core to cladding thickness ratio T c :T d . The multi-layer glass melt (300) is directed onto the surface of a molten metal bath (162) contained in a float tank (160). The width W m of the multi-layer glass melt (300) is less than the width W f of the float tank (160) prior to the multi-layer glass melt (300) entering the float tank (160). The multi-layer glass melt (300) flows over the surface of the molten metal bath (162) such that the width W m of the multi-layer glass melt (300) increases, the melt thickness Tm decreases, and the core to cladding thickness ratio T c :TC i remains constant as the multi-layer glass melt (300) solidifies into a laminated glass sheet.
