The float test will probably not work after water glassing.I wonder if the float test would work after water glassing
Many say on a normal egg that’s been in fridge or counter to test if they are still good you put them in water
If it sinks it’s good. If it floats it’s old
For eggs that have been stored somewhere dry, the air cell gets bigger over time, because water evaporates from the egg. The bigger air cell is what makes the egg float. A floating egg means a big air cell, which means an old egg (but does not tell if the egg has rotted or spoiled, only that it is old enough that it lost a lot of moisture and now has a big air cell.)
For eggs stored in water glass, where they are submerged in liquid, the air cell should not get any bigger, no matter how long they are in there. So there would be nothing to make them float.
