How to Preserve Eggs Without Refrigeration

How to Preserve Eggs Without Refrigeration


Eggs are a great source of protein and a staple in many diets. However, they can be challenging to store for an extended period without refrigeration. In this article, we’ll explore various methods of preserving eggs without the need for a fridge. These methods are not only useful for preppers but also for individuals seeking alternative ways to store eggs.

When it comes to preserving eggs, the key is to create an environment that inhibits the growth of bacteria and prevents spoilage. Below are three effective methods for preserving eggs without refrigeration:


The Water Glass method, also known as sodium silicate preservation, is an age-old technique that involves submerging eggs in a water glass solution. Follow the steps below to preserve your eggs using this method:

  • Start by finding a suitable container. It should be large enough to hold the eggs and the preserving solution.
  • Prepare the preserving solution by mixing one part sodium silicate (water glass) with ten parts water. You can find sodium silicate at most hardware stores or online.
  • Gently place the eggs into the container, making sure they are not cracked or damaged.
  • Pour the preserving solution over the eggs, ensuring they are completely submerged.
  • Cover the container with a lid or plastic wrap to prevent evaporation.
  • Store the container in a cool and dark place, such as a root cellar or a basement.

Your preserved eggs should last for up to nine months using the Water Glass method. Remember to check the eggs for freshness before consuming them. Discard any eggs with an off smell or unusual appearance.


Coating eggs with mineral oil is another effective method of preserving them without refrigeration. Mineral oil creates a barrier that prevents air from entering the egg and slows down spoilage. To use this method, follow the steps below:

  • Inspect the eggs for any cracks or damage. Discard any eggs that are not in good condition.
  • In a bowl, pour enough mineral oil to completely cover the eggs.
  • Gently roll each egg in the mineral oil, ensuring it is fully coated.
  • Place the coated eggs in a clean carton or basket.
  • Store the eggs in a cool and dry location.

When stored in mineral oil, eggs can last for up to six months. Remember to turn the eggs once a month to prevent the yolk from settling and sticking to the shell.


Burying eggs in a homemade limestone paste is another clever way to preserve them without refrigeration. Here’s how to do it:

  • Mix equal parts of hydrated lime (also known as pickling lime) and water to create a paste.
  • Gently coat the eggs with the limestone paste, ensuring they are well-covered.
  • Place the coated eggs in a clean container, making sure they are not touching each other.
  • Cover the container with a clean cloth or towel to allow for air circulation.
  • Store the container in a cool and dry place.

Eggs preserved in limestone paste can last for several months. However, it’s important to note that the taste of the eggs can change slightly due to the alkaline nature of the limestone paste.


Preserving eggs without refrigeration is a valuable skill to have, whether you’re a prepper or simply looking for alternative storage methods. These three methods – water glass, mineral oil coating, and burying in limestone paste – can help extend the shelf life of your eggs and reduce waste. Remember to always inspect eggs for freshness before consuming them and discard any that appear spoiled. Happy egg preserving!
