Earlier than refrigeration grew to become commonplace, submerging eggs in water glass was the popular technique of storage. Water glass, also referred to as sodium silicate, is a glassy strong (silicon dioxide) that dissolves in water. It has quite a few industrial makes use of, together with as a meals preservative and a desiccant (silica gel pack) to guard delicate objects from absorbing moisture. Liquid water glass is a syrupy, concentrated answer of sodium silicate. It’s main use by owners is to seal concrete.
Equally, the aim of liquid water glass as an egg preservative is to seal the shell’s pores to attenuate evaporation from the egg and inhibit micro organism from coming into. Water glass imparts no style or odor. It causes a silica crust to develop on the skin of the shell, however doesn’t penetrate the shell.

Beneath the very best storage circumstances, eggs lose a few of their contemporary taste and grow to be bland tasting over time. The whites will ultimately get skinny, and the yolks will flatten when cracked right into a pan, making them much less appropriate for frying or poaching than for scrambling or incorporating into recipes. No matter their age, a good suggestion is to crack every egg right into a cup or small bowl earlier than utilizing it, to make certain it nonetheless seems and smells contemporary.
Is Storing Eggs in Water Glass Protected?
Pennsylvania State Extension says: “We can not suggest the usage of water glass for the reason that security of merchandise preserved utilizing this ingredient has not been evaluated scientifically.”
Then again, Oregon State Extension says: “You may lengthen the shelf lifetime of eggs by storing them in a compound often called water glass.”
Quite a few anecdotal accounts of households that saved eggs in water glass previously, or that presently achieve this, could also be discovered on-line. They point out that the apply is protected and retains eggs contemporary for as much as two years. Nevertheless it bears repeating that the eggs should be same-day contemporary and clear from the nest.
