What each ingredient does

Eggs
The main food being preserved; the solution surrounds them so they keep without refrigeration.
Silicate of soda (water glass)
Forms a sealing layer that blocks air from reaching the eggs, slowing spoilage.

The step that matters

Fully immersing the eggs. Any egg left above the liquid is exposed to air, which can let spoilage start. Keeping every egg covered by the solution keeps the seal intact over storage.
