Water-Glass Method
A good method for the preservation of eggs is the use of sodium silicate, or water glass. If the price of sodium silicate is about 30 cents a quart, eggs may be preserved at a cost of approximately 2 cents a dozen. It is not desirable to use the water-glass solution a second time.
Use 1 quart of sodium silicate to 9 quarts of water that has been boiled and cooled. Place the mixture in a 5-gallon crock or jar. This will be sufficient to preserve 15 dozen eggs and will serve as a guide for the quantity needed to preserve larger numbers of eggs.
(1) Select a 5-gallon crock and clean it thoroughly, after which it should be scalded and allowed to dry.
(2) Heat a quantity of water to the boiling point and allow it to cool.
(3) When cool, measure out 9 quarts of water, place it in the crock, and add 1 quart of sodium silicate, stirring the mixture thoroughly.
(4) The eggs should be placed in the solution. If sufficient eggs are not obtainable when the solution is first made, additional eggs may be added from time to time. Be very careful to allow at least two inches of the solution to cover the eggs at all times.
(5) Place the crock containing the preserved eggs in a cool, dry place, well covered to prevent evaporation. Waxed paper covered over and tied around the top of the crock will answer this purpose.
