Everyone is also forgetting directional freezing. When you freeze ice cubes they are small enough that you freeze the entire thing rather rapidly and since water freezes outside in if you freeze from all sides equally it traps impurities. If you insulate 3 sides and have a bigger container than just your normal ice tray you can slowly freeze from the top down. This let’s the impurities stay in the water as the top layer becomes clear ice.
