Waterglassing eggs is an old method of preserving eggs. In times of abundance, this is a great way to use eggs up for future consumption.
Waterglassing Then and Now
Waterglassed eggs consists of making a solution that your pour over your eggs and keep covered and stored somewhere in your home. The process was originally done using sodium silicate. This is used in concrete sealer, to waterproof walls, and make fabrics fire retardant. It’s a pretty sticky method of preservation and, in my opinion, not the best option if you’re wanting to reduce chemicals in your home.
Today, waterglassing is done using calcium hydroxide, also known as cal lime or pickling lime. Personally, I am a lot more comfortable with this option!
How To
To start, you need fresh eggs that are unwashed. They need to be clean, but do not get them wet. You want the natural bloom, or protective bacterial coating, present on the egg. This is not the time to use the nasty eggs. You want the cleanest eggs from the nest for this project.
Next, make sure you have a food grade container for storing your eggs. This can be a food grade bucket or a glass jar. Stack your eggs carefully in your container.
Now, measure out 1 ounce of calcium hydroxide by weight. Use a food scale like this one. Add this to 1 quart of filtered water in a measuring cup and whisk together. Pour the solution over the eggs. If your eggs are not completely submerged, mix up more solution and pour over. Do this until all eggs are submerged.
Finally, cover the container and store in a low traffic area so it won’t get bumped. These eggs will last 6-12 months, maybe even longer!
Using Your Waterglassed Eggs
To use your waterglassed eggs, all you’ll need to do is rinse them well. You want to get the cal lime off so that when you crack it, it doesn’t fall into your food. The only difference I’ve noticed with waterglassed eggs, is the yolks seem to break more easily. This makes them not the best option for a fried egg when you want the yolk to hold together. The older the are, the more prevalent a “loose” yolk will be.
Other than that, they’re just the same! Use them as you’d like.

Waterglassing eggs preserves them for months and months! Try this preservation method to have eggs all year long!
Instructions
- Weigh one ounce of calcium hydroxide.
- Measure one quart of filtered water. Add your calcium hydroxide and whisk well.
- Pour over your eggs. If your eggs are not completely submerged, mix up another batch of the solution. Pour over until your eggs are completely covered.
- Store for 6 months to a year. Put them in a place where they won't get bumped or cracked.
