Glass in the freezer: Yay or Nay?

Just a quick correction: liquids in general do not expand when they freeze; they contract. Water is very unusual in that it's one of the only liquids whose density reaches a maximum above its freezing point :)

(This is why ice floats on water but the frozen form of other liquids does not.)

in a freezer? what ever the temp is set to.

You are right, but I can't think of one food/drink item that is not water based :p
 
Nothing wrong with it at all.

Infact, one of my favorite things I remember about the first time I went to America when I was a kid is that a lot of bars & restaurants, when you order a soft drink or beer, they will bring it in a large frosted mug. Quite easy to do, just take a large thick glass mug, ensure its dampened with a thin layer of water and allow it to freeze.
 
Slightly Off Topic - but I read the thread title and thought there's nothing better on a hot sunny summers day than a cold beer especially when the pint beer glass has just come out of the freezer! :cool:

well yeah, but you don't have 100% ethanol :p



40% spirits freezes at - 29-30c.
and when alcoholic drink freezes alcohol is contained in the crystals, so the liquid part does not get stronger.

Not totally true, they use the freezing method to make the brew dog stuff by cold distilling (something like that) to concentrate it to 32/42%

Freeze distillation.

Such enrichment by freezing of a solution in water is sometimes oversimplified by saying that, for instance, because of the difference in freezing points of water (0 °C/32 °F), and ethyl alcohol (-114 °C/-173 °F), "the water freezes into ice...while the ethyl alcohol remains liquid." This is false, and although some of the implications of that description are true and useful, other conclusions drawn from it would be false.

The detailed situation is the subject of thermodynamics, a subdivision of physics of importance to chemistry. Without resorting to mathematics, the following can be said:

* Freezing in this scenario begins at a temperature significantly below 0 °C.
* The first material to freeze is not the water, but a dilute solution of alcohol in water.
* The liquid left behind is richer in alcohol, and as a consequence, further freezing would take place at progressively lower temperatures. The frozen material, while always poorer in alcohol than the (increasingly rich) liquid, becomes progressively richer in alcohol.
* Further stages of removing frozen material and waiting for more freezing will come to nought once the liquid uniformly cools to the temperature of whatever is cooling it.
* If progressively colder temperatures are available,
o the frozen material will contain progressively larger concentrations of alcohol, and
o the fraction of the original alcohol removed with the solid material will increase.
* In practice, unless the removal of solid material carries away liquid, the degree of concentration will depend on the final temperature rather than on the number of cycles of removing solid material and chilling.
* Thermodynamics gives fair assurance, even without more information about alcohol and water than that they freely dissolve in each other, that
o even if temperatures somewhat below the freezing point of ethyl alcohol are achieved, there will still be alcohol and water mixed as a liquid, and
o at some still lower temperature, the remaining alcohol-and-water solution will freeze without an alcohol-poor solid being separable.

Just put whatever you are storing in a plastic bottle (and leave a little room for expansion) , you can store milk for example in the freezer no problem.

edit - vodka is fine in glass as others have said
