Is it possible to make very clear ice in a home freezer? Tap water ice is often cloudy white, which I think comes from minerals in tap water. Making ice with distilled water is a pretty conclusive experiment, I think. However, the ice cubes I make with distilled water still have many small air bubbles frozen into them. I have tried melting and re-using the ice in the hope that there would be less dissolved air in the water on subsequent freezings, but it did not seem to make a difference. By examining cubes as they are freezing, you can see that the top gets cooled the most, and this skin of ice can trap air. I have tried putting the water in bit by bit. With a thinner layer of water, I expected the air might reach the top before the water freezes. There are still bubbles. I put a container with a small hole in it above a dish. I filled the container and let the water drip out. I cooled the water in the container first, in the hope the drops would freeze rapidly. The hole froze shut before the container could empty, but the ice in the dish below still had air bubbles.
