The white color in ice is due to dissolved gas, minerals, and impurities. As ice freezes, it actually crystallizes and excludes impurities, but in small quantities, there is nowhere for them to go. Here is how to prove this and produce perfectly clear ice.
Place a large bowl of water in the freezer and let it freeze. Remove it and you will see that the center is white and bubbly while the outer portions (that froze earliest) are very clear. If you break off the clear portions and separate them from the white portions, you can do a simple experiment.
Take two glasses, put the perfectly clear ice in one and the white ice in another. Let both melt. Taste the water from each. You will find that the clear ice produces excellent drinking water, while the white ice makes unpleasant tasting water. Both are safe to drink, but one has impuritites and dissolved gas that change the flavor. You have now sucessfully purified water using a freezer.

the white has nothing to do with the water. To get clear ice you need to have the freezer at a certain temp. the white of ice is actually frozen air as the water freezes to quickly it traps the air inside

bubbles!! (and then properties of light too. when light travels through substances with different indicies of refraction (solid has air and water in it), the reflected and refracted colors will be different than before)

Eh what? Ever seen the glaciers or the icebergs? They're really blue!
