A good method for the preservation of eggs is the use of sodium silicate, or water glass.

The water is slightly alkaline and resembles a very dilute solution of sodium silicate (water glass).

It is very refractory, and is applied by mixing with water and some bond, such as sodium silicate or gas-tar.

Eggs are submerged in lime-water or a dilute solution of sodium silicate (soluble glass).

The residue is well washed, ignited, and weighed as SiO2, and from this silica is calculated the sodium silicate.
