Answer:
No it will not be transparent.
Explanation:
Glass composition (Normal float glass) has some iron impurities due to which you always see a unique greenish blue tint if you see the thickness of the glass. This tint goes on concentrating as the stack grows bigger and bigger. Like when we get a stack packed in wooden box with say about 25 sheets of 5mm thickness – we cannot see through clearly. After a point it just looks like a green block. Hope it helps.
