What each ingredient does

Eggs
The main food being preserved; they are fully covered so the liquid can keep them intact.
Water glass
Sodium silicate that forms an alkaline, protective solution around the eggs, slowing spoilage.

The step that matters

Fully immersing the eggs. Any egg left above the liquid can spoil, because air and microbes reach it. The mixture should be cooled before pouring so it does not heat or crack the shells, and every egg must sit below the surface.
