Answer:

Careful tests have been made with various compounds, and Water Glass has in each case proven most satisfactory. It is also called Soluble Glass.

The chemical name is silicate of sodium or silicate of potassium. It can be purchased at any drug store, and costs about 50 cents per gallon, which is sufficient to preserve 50 dozen eggs.

To one quart of Water Glass add ten quarts of water. It is best to use water that has been boiled and is perfectly clean.

The eggs should be wiped clean, but should not be washed. Earthenware jars are best for storing the eggs, which should be entirely submerged in the liquid.

If wooden barrels or kegs are used, see that they are first thoroughly scalded with boiling water.
