It would have to be in water, as sodium silicate is a solid.
Most of the chicken egg is actually not alive in the sense that it is made up of cells. Most of it is food for the (maybe to be) fertilized egg which is tiny. It’s nourishment for the expected growing chicken.
The unfertilized egg we buy in the supermarket would contain one female egg cell. It’s only when it’s combined with the papa chicken’s cell that it starts dividing and consuming the part of the egg we enjoy with our bacon.
The sodium silicate I bought was a thick liquid form, in a quart jar. I think it was actually marketed to seal masonry.
And I did use eggs from a flock (rooster included). In my life, I have seldom used store bought eggs.
