Answer 1

My dad actually fixes these machines and we share an office. Our ice machines at home /ice trays at home just drops water into a small ice tray and freezes it. A lot of air gets trapped and that’s the white you see.

The very expensive clear ice machines have water constantly running over a very cold plate, and the cold plate freezes the ‘bottom most’ water until everything is frozen. The method of ‘running’ also ensures that air doesn’t get trapped and turn the ice white. These industrial Machines are incredibly expensive, though.
