Abstract:
A glass plate made of soda lime silica glass containing at least MgO, CaO, Na2O and Al2O3 produced by a float process or a downdraw method, wherein [MgO] is at least 4.5%, [MgO]/[CaO] is larger than 1, and Q=([MgO]/[CaO])×([CaO]+[Na2O]−[Al2O3]) is at least 20, wherein [MgO] is the content of MgO, [CaO] is the content of CaO, [Na2O] is the content of Na2O, and [Al2O3] is the content of Al2O3 (each being as represented by mass percentage based on oxide) and a process for the glass plate.
