Why must the glass stopper of a reagent bottle never be placed directly on the laboratory bench?

The stopper of a chemical reagent container should be handled carefully for two reasons. Firstly, it may contain chemical residues which can be dangerous. Additionally, if the stopper is dirtied it may contaminate the reagent in the bottle when the stopper is put back on.

When glass stopper in a bottle is stuck it may sometimes be loosened by holding the neck of the bottle under a hot water faucet explain the physical principle responsible for this observed phenomenon?
With a few exceptions (notably melting ice) objects expand when heated. If you run hot water on a bottle neck, the heat is applied directly to the bottle and only indirectly to the stopper inside the bottle, so the bottle heats first, and thereby expands sooner than the stopper does. An expanded bottle will exert less pressure on the stopper.
