You do realise that cement contains corrosive bonding agents from Sand originally.
Glass manufacturing also still is involved with Sand, although glass these days is stronger in some ways, in that it doesn't break so easily thus it is made more flexible. Antique glass brakes easier because it's more brittle.
But the contradiction is that modern glass scratches easier than antique glass.
The reason? The surface of new glass ends up soft, whereas the surface of antique glass is hard.
But you knew that already, didn't you?
