How/why does ice “stick” to any cup it’s been frozen into, regardless of cup material?

Not sure whether to file as chemistry or physics, since I’m not sure if it’s because the ice is somehow binding to the plastic/glass, or if it has to do with it being a “perfect fit” in terms of imperfections… or if it’s something else entirely

Large chucks of ice retain a colder temp at the core. As ice is pressed against the side of the vessel the outside melts into water but re-freezes once it chills the surface. Small chunks won’t do this, as they do not retain a cold enough core to get the surface cold enough to re-freeze the initial melt.
