How to preserve eggs – Water glassing

How to.., Recipes for your chooks

Have you ever tried preserving🥚 eggs? If your flock aren’t laying now, you’ll be wishing you had done this over Summer!

Water glassing is a quick and easy method of preserving your fresh eggs for up to a year (or more!) using just water and pickling lime (calcium hydroxide). This does not pickle the eggs. The end result is raw, usable eggs.

The recipe itself is simple. Basically, you mix pickling lime with water and place your eggs into the solution, which preserves the eggs. Months later you can enjoy fresh eggs as if you just plucked them from the coop.

Any type of poultry egg can be preserved using the water glassing method. The eggs must be fresh, clean of any debris, but unwashed (unwashed is important!). You cannot use store-bought eggs for water glassing because eggs from the store have been washed and bleached, which destroys the egg’s bloom coating.


  • 5 litre food-grade bucket
  • 60 grams Hydrated Lime
  • 2 litres of Filtered Water
  • Fresh Eggs
  • Clean Jar

1. Start off with a clean bucket to store your eggs. 
2. Add enough water to your container so that your eggs will be completely submerged, but not so much that the water will overflow.
3. Measure out your water and lime. The ratio of water to lime is for every one litre of water you’ll use 30 grams of lime. No matter what size container you’re using, this is the ratio to follow.
4. Add the lime to your clean water and whisk until completely dissolved. The water will look milky white.
5. Gently add your unwashed fresh eggs.
When you get to the point where you can start positioning eggs, be sure you’re putting the pointy/small side down.
6. When you’re ready to use your eggs, simply remove them as you need them, give them a good rinse off and use them as normal. 

The reason we point eggs down is that there’s an air pocket in each egg, so if you have it going toward the largest size, it’s not touching as much of the egg white and you’ll end up with a better quality egg.
The biggest concern with water glassing eggs is evaporation. You don’t want your lime water evaporating and exposing your eggs, especially if you’re storing them away in the basement where you might forget about them.
One way to keep evaporation from happening is to use a container with a lid. If your container doesn’t have a lid, you could add a layer of olive oil over the top of the water, then cover with a towel to keep any bugs or insects out. 

What is hydrated lime?
Hydrated lime is usually a combination of oyster shells, bones, and limestone that have been burnt in a kiln, then hydrated with water. That’s it! It’s a very natural product, it’s not synthetic, and it’s completely safe to use.
Do note that hydrated lime will be very different than the lime you’d find in your agricultural section at the local hardware store, so be sure you’re sourcing the correct product.
