1. Float glass comprising:
a float glass composition that includes:Ingredient(wt. %)SiO2 67-69.5%A12O32.5-4.5%(SiO2 + A12O3)<73%Na2O16.6-20% K2O0.5-2.0%CaO4.0-7.0%MgO2.5-3.5%CaO + MgO 6.5-10.5% wherein the float glass is chemically strengthened and has a depth of layer, which is depth of a compressive stress layer in the glass resulting from the chemical strengthening, with a 4 hour chemical strengthening process at 435 degrees C. being used as a reference, of at least 25 μm. |
