Re: What happens when you freeze an Egg ?

Matthew,

	A raw egg is mainly fats and proteins dissolved and/or suspended in 
water, so if there is going to be any change in density then it will expand 
upon freezing like all water-based solutions.  However, I am not sure if it 
will expand sufficiently to crack the egg's shell.  The easiest way to test 
this is to just put several raw eggs in the freezer (you always want to run 
an experiment with several data points, in this case eggs) and see what 
happens.  Let it go overnight or all day, since it will take a while to 
freeze and you want to be sure you're looking at a truly frozen egg.

	I don't think you could see through a frozen egg (if you were able to 
get it out of the shell) because a lot of the proteins in the egg "white" 
part (which is clear when raw and unfrozen) are going to unfold and/or 
precipitate due to the freezing process, and this will make the egg white 
cloudy, but again I don't really know and the best way for you to test this  
is to carefully peel your frozen eggs after about 24 hours (only take out 
one at a time from the freezer so the others don't thaw while you are 
trying to peel one) and try to look through them.

	Good luck and feel free to email to me directly if you have any further 
questions.
