34. PRESERVATION WITH WATER GLASS.--Putting eggs down in a solution of
water glass is without doubt the most satisfactory method of storing
them in the home. So effective does this method prove that the housewife
who has a convenient and proper storage room should not fail to take
advantage of this way of laying up a supply of eggs.
The commercial form of water glass is usually a mixture of potassium and
sodium silicate, which, besides being cheaper than that which is
chemically pure, is the kind that is preferred for the purpose of
preserving eggs. A good quality of it either in a sirup-like solution or
in the form of a powder retails in drug or grocery stores for about 10
cents a pound. To make a solution of the desired strength to preserve
eggs satisfactorily, dissolve 1 part of water glass in 7 parts of warm
water that has first been boiled to drive off bacteria, mold, spores,
etc. One quart of water glass will make sufficient solution to cover
about 12 dozen eggs. With the solution thoroughly mixed, it is ready to
pour over the eggs.
In selecting eggs for the purpose of storing, be careful to choose only
those which are clean, fresh, and perfectly sound, and, if possible,
infertile. It is advisable not to wash them before they are put into the
preservative, for they will keep better if their bloom is not removed.
Place the eggs in receptacles in the manner explained for preserving
eggs in limewater, and over them pour the water-glass solution until
they are all covered.
