Abstract: 1,209,041. Bending chemically tempered glass sheet. GLAVERBEL. 1 Dec., 1967 [28 April, 1967], No. 54763/67. Heading C1M. A sheet of glass is permanently bent by applying bending forces to convexly bend a compressively stressed surface of the sheet after it has been chemically tempered and whilst the viscosity of the glass is at least 10<SP>10</SP> poises. In a preferred embodiment a flat glass sheet is vertically suspended in a bath 8 of a molten metal salt (e.g. potassium nitrate, or a mixture of sodium chloride, sodium nitrate and lithium nitrate) heated to a temperature of 560‹ to 580‹ C. for a predetermined period to give a desired degree of temper. The sheet is then lifted from the bath and laid horizontally on a movable bending die 11. The die is then moved into a furnace 14 to beneath a pair of bending members 29. The members 29 are mounted in a pair of horizontal cross members 25 the ends of which engage vertical screw members 24, which when rotated lower or raise the bending members 29 into or out of engagement with the two ends of the glass sheet and bend it to the shape of the die. After bending the sheet is transferred to another bath containing molten metal salts, but at a lower temperature than the first bath and is subject to a final tempering step. The bending is preferably done when the glass viscosity is in the range 10<SP>11.5</SP>-10<SP>14À5</SP> poises. In an alternative embodiment the glass is lowered into a bath of molten metal salts on its bending die. This can either follow a first tempering step in a bath such as 8 above or the sheet can be tempered in the bath and then pressed to shape whilst still within the bath. The tempering can be done by any of the conventional ways including use of a contacting medium such as gases. Examples of glasses are (i) SiO 2  70%, Na 2 O 12%, CaO 10%, MgO 3%, Fe 2 O 3  trace, Al 2 O 3  5%; (ii) SiO 2  60%, Na 2 O 12%, CaO 10%, MgO 6%, B 2 O 3  6%, P 2 O 5  1%, Al 2 O 3  5%.
