Water Glassing Eggs

Springtime on the homestead means more daylight, and happier chickens. Happier chickens make more eggs, and thus, we have an overabundance to deal with. In order to have plenty in the fall and winter months, water glassing eggs is the perfect solution.

What is Water glassing Eggs?

Water glassing eggs involves submerging clean, unwashed, eggs in a pickling lime and water solution to seal off the shell and preserve them for 12-18 months. The result is perfectly fresh, unspoiled eggs, just like they were the day the hen laid them. Sometimes properly water glassed eggs are still fresh even after two years. Homestead folks have been using this preservation method since the 1800s to capitalize on the springtime egg abundance year round.

There are a few different solutions that work for water glassing, such as sodium silicate and water, but today I am going to share a method for using hydrated lime, which is also known as pickling lime.

Tips:

You can fit approximately 16-18 eggs per half gallon jar.

Use your cleanest eggs for water glassing. I usually set aside the spotless ones and wait to water glass until I have enough of them. We wash the really dirty ones and store them in the refrigerator. If we keep up with cleaning the coop, and adding fresh straw or bedding, we have a lot more water glass candidates.

If you don’t have a water filter, and you only have access to chlorinated water, you can leave an open jar of water out on the counter for 24 hours. This will cause the chlorine to evaporate.

Use an airtight vessel. Oxygen is the enemy of nearly all food preservation methods, and water glassing is no exception!

Use 1 ounce of pickling lime per quart of water. You can do this in any quantity. So if you have 50 dozen eggs, get yourself some big old food grade buckets and whole lot of lime!

FAQ

Why should you preserve eggs?

We don’t usually think of eggs as a seasonal food, but they actually are. A hen’s ovulation coincides with the length of the day. In the winter, when the daylight hours are short, hens lay little to no eggs. Chickens reach their peak egg laying production when the daylight hours are longest. Heat can also affect ovulation, so springtime, between April and June, yields the highest egg volume here on our homestead. In order to avoid buying several dozen eggs a week in the middle of winter, it makes sense to preserve them when production is up.

Can you water glass store bought eggs?

Unfortunately, no, you cannot water glass store bought eggs. When hens lay eggs, they are covered with a protective “bloom” to keep the eggs fresher longer. This is the reason you can find a pile of eggs hidden somewhere on your homestead after a few weeks, and they are still perfectly fresh and edible. Eggs from the grocery store have been thoroughly cleaned and sanitized, so the bloom is no longer in tact. The lime solution in water glassing works with the bloom to preserve the eggs, so sanitized eggs are a definitee no-go for this method. Try freezing the eggs instead.

Can you use tap water to water glass eggs?

Avoid chlorinated and fluorinated water when water glassing eggs. Ideally you would have access to filtered water that still has all of the minerals intact. If you are on a well, tap water will work just fine. If you are on city water with chlorine and fluoride, opt for a filter, such as the Berkey Water Filter for water glassing eggs.

Can you boil water glass eggs?

You can hard boil eggs that have been water glassed, but it is important to note that you should first poke a small hole in the shell. The hydrated lime solution works by sealing off the egg, and filling all of the pores of the eggshell, so it could actually explode if you don’t first create a release for the pressure.

What is hydrated lime?

Hydrated lime aka calcium hydroxide is a dry and colorless white powder that is most commonly used in steel manufacturing. It is also known as pickling lime or slaked lime.

Can I use garden lime for water glassing eggs?

Garden lime is calcium carbonate, whereas pickling lime is calcium hydroxide. Since the hydroxide is more alkaline, pickling lime is recommended for water glassing.

Is it normal for the lime to settle on the bottom?

Yes, settling lime is a normal part of the process. You may be tempted to stir the solution back up, but don’t do it! You risk cracking the eggs and ruining the whole batch. There is still plenty of lime in the water to preserve the eggs, so no need to worry.

Are water glassed eggs safe to eat?

As long as the process was done properly, water glassed eggs are perfectly safe. Make sure to use clean jars and utensils and clean unwashed eggs. If an egg has gone bad, you will know. The smell will be way off. You can also use the float test to ensure the egg is still fresh.

Do they taste different than fresh eggs?

No! That is the best part about water glassed eggs. Freezing and dehydrating eggs changes the texture of the eggs, whereas water glassing keeps them exactly as they were the day the hen laid them.

When can I preserve farm fresh eggs?

Do you have an overabundance of eggs in the winter for some reason? No worries! You can use water glassing anytime. The eggs also don’t need to be harvested fresh that day. You can wait until you have enough clean ones saved up and do a big preserving day anytime!

Ingredients you will need:

1 ounce pickling lime

1 quart filtered water

Clean unwashed eggs (Eggs that have no poop or mud, and the “bloom” still fully intact)

Equipment:

Airtight Food grade bucket or half gallon glass jar

Kitchen scale (to weigh the pickling lime)

What types of eggs can you use:

Chicken Eggs

Quail Eggs

Duck Eggs

Any eggs can we water glassed!

How To Water Glass Eggs:

Measure out 1 ounce of pickling lime on your kitchen scale.

Add the pickling lime to a clean half gallon jar and fill it up halfway (one quart) with filtered water.

Whisk the lime into the water until it is fully incorporated.

Carefully add the eggs pointy side down.

Add an airtight lid to prevent oxygen from getting in, and prevent the water from evaporating.

Store the water glassed eggs in a cool dark place.

How Long Do They Last?

You can store water glassed eggs in a cool dark place for up to a year. Some people have had success for much longer.
