1. The problem statement, all variables and given/known data
What does a piece of glass stick to another piece of glass? We conducted a demo in school where we stuck to pieces of identical see-through glass on top of each other and they stuck together for a second or two.

2. Relevant equations
None whatsoever other than it was about "Over Polished" Substances

3. The attempt at a solution
It sticks due to their friction

Draw a free-body diagram and indicate where atmospheric pressure exerts forces. How much "atmosphere" exists between two pieces of identical highly-polished pieces of glass?
