What if there were no spoon, Neo?

I sometimes make iced coffee by placing a glass mason jar filled with ice into my single serve coffee maker and letting it brew / fill with hot coffee. I include a metal spoon inside the jar to act as a kind of heat sink and prevent the glass from breaking due to thermal stress. But should I bother? Does that spoon actually do anything?
