Water glassing eggs is an ideal preservation method ensuring nutrient-rich eggs all year round. A sodium silicate or calcium hydroxide, (pickling lime) solution protects eggs from bacteria, offering a fresh taste despite the storage duration. A simple process with outstanding benefits for self-sustainability.

Introduction

Water glassing is a long-standing and effective technique for preserving fresh eggs without refrigeration. This method, originating from a time before refrigerators were commonplace, involves submerging fresh eggs in a solution of water and sodium silicate, commonly known as “water glass.” The sodium silicate coats the eggshells, effectively sealing them off from oxygen and bacteria, thereby keeping the eggs fresh for an extended period, sometimes up to a year or more.

Importance and Benefits of Water Glassing Eggs

Preserving eggs through the water glassing method holds considerable importance, particularly in areas where electricity for refrigeration is unreliable or for those seeking self-sufficiency. This technique reduces dependency on refrigeration, thereby promoting sustainability and saving on energy costs. Moreover, water glassing allows for the preservation of surplus eggs during times of plenty, ensuring a steady supply during lean periods. The method also preserves the taste and nutritional value of the eggs, unlike other preservation techniques that can alter these characteristics. For homesteaders, survivalists, or anyone interested in traditional food preservation methods, water glassing offers an economical and effective solution for storing fresh eggs.

Materials Needed for Water Glassing Eggs

Fresh, unwashed eggs – It’s essential to use fresh eggs and not wash them as washing removes the natural protective bloom on the eggshell.

Sodium silicate or pickling lime (calcium hydroxide)- The key ingredient for creating the preserving solution

Water – You’ll need clean, cool, and preferably distilled or spring water to mix with the sodium silicate or pickling lime. If you have neither, tap water will suffice but may affect the taste of your eggs.

A vessel or jar with a tight-fitting lid – You can use any glass or food-grade plastic container as long as it has an airtight seal to prevent oxygen from entering.

Choosing the Eggs

When choosing eggs for water glassing, it’s crucial to select fresh ones, ideally gathered within the last couple of days. The eggs should be free from visible cracks or defects in the shell, as any damage could compromise the preservation process. Do not wash the eggs before water glassing. The natural “bloom” or coating on the shell acts as a barrier against bacteria and moisture, aiding in preservation. Prefer eggs from hens that are free-range or organically fed, as these tend to have stronger shells and a higher nutritional content, which can enhance the preservation process. Finally, ensure the eggs are normal-sized; avoid using overly large eggs as the size can affect the egg-to-water glassing solution ratio.

Preparing the Water Glassing Solution

Preparing the Lime-Water Solution

Follow these steps to prepare the lime-water solution for water glassing eggs:

1. Ensure you have your safety gear (gloves and protective eyewear) on before starting the process.
2. In a large pot, pour one quart of clean, cool water.
3. Slowly add one ounce of pickling lime, stirring continuously with a long-handled spoon. It’s essential to add the lime to the water and not the other way around to avoid any chemical splashes. The ratio is one ounce to each quart regardless of how many quarts you prepare.
4. Keep stirring until the pickling lime completely dissolves in the water. This creates your lime-water solution.
5. Let the solution cool before use.
6. Once cooled, carefully pour the lime-water solution over the eggs in your chosen container, ensuring that the eggs are completely submerged. The eggs should be covered by at least an inch of solution.
7. Cover the container with a lid or cloth to protect it from dust and any potential contaminants.

Remember to be patient as the pickling lime might take a while to fully dissolve in the water. If you see some undissolved lime settling at the bottom of your container, don’t worry. It also may initially look a bit milky. This is normal and will not affect the preservation process.

Preparing the Sodium Silicate Solution

Follow these steps to prepare the sodium silicate solution for water-glassing eggs:

1. Equip your safety gear, including gloves and protective eyewear, to protect yourself from any chemical reactions.
2. In another large pot, pour one quart of clean, cool water.
3. Gradually add two ounces of sodium silicate, stirring steadily with a long-handled spoon. Just like with the lime, always add the sodium silicate to the water and not vice versa to prevent splashing.
4. Continue stirring until the sodium silicate is wholly dissolved in the water, forming your sodium silicate solution.
5. Allow the solution to cool to room temperature before using.
6. After cooling, carefully pour the sodium silicate solution into the same container that will hold the eggs . Ensure that all eggs remain fully submerged with an extra inch of solution covering them.
7. Secure the container with a tight-fitting lid or clean cloth to protect from dust and other contaminants.

Patience is the key here, as sodium silicate might take some time to dissolve completely in the water. It’s not unusual to witness undissolved sodium silicate at the container’s bottom; this is a normal occurrence and will not impact the preservation process.

Which solution is best to use calcium hydroxide(pickling lime) or sodium silicate?

While both calcium hydroxide (pickling lime) and sodium silicate are effective for water-glassing eggs, there are some differences to consider when choosing which solution to use.

Calcium hydroxide is a traditional and widely used method for preserving eggs. It is affordable and easily accessible as it can be found in most grocery or hardware stores.
