What each ingredient does

Water glass (sodium silicate)
Makes an alkaline, sealing liquid that slowly cures the eggs by limiting air and moisture loss through the shell.

The step that matters

Keep the eggs fully submerged. Any egg exposed to air dries out and spoils unevenly, so the liquid must stay above the eggs as the level drops and more is added.
