Title says it all really, the store brought ice is always very different. Why is this?
Edit: I know I’m a moron, bought*
In: Chemistry
They use a different process to make ice more efficient and quickly. Instead of putting the water into a freezer and cooling it with air they spray/pour water directly on the coils of the freezer. This makes it form in a bunch of thin and quickly formed layers, instead of as one thick chunk which is frozen slowly over dozens of minutes.
When ice is formed in a big chunk it freezes from the outside in. So a layer on the outside forms, and then the inside of it is stopped from expanding and can’t push itself out, which makes a bunch of stress lines/fractures throughout the cube. This is also why ice cubes from your freezer will ‘pop’ or sometimes explode when it’s melting in your glass.
None of this happens when the ice is formed in layers from one direction because the water has room to expand.
