What each ingredient does

Sodium silicate
Forms an alkaline, gel-like layer that slows air and microbes from reaching the egg.
Eggs
The food being preserved; the solution fills the shell's pores to slow spoilage.

The step that matters

Ensure eggs are not floating; discard any that do.. Floating eggs have larger air cells, usually because they are older or cracked. Those eggs spoil more readily, so removing them protects the rest of the batch.
