Has anyone ever used KePeg Egg Preserver?

Interesting! I wonder if it really works?  Maybe someone will chime in..

My mom use to talk about my grandmother doing something with her eggs, called an "egg well".  she would submerge the eggs in something, I thought it sounded like some kind of gel or something, but mom never really knew what it was.  She would do it for the wintertime, when eggs were more scarce. This would have been in the 1930's probably . . .but mom said the eggs would keep for a long time in the stuff. . .wonder if its the same thing.  This is the first time I have EVER seen anything like this and have been asking people for years!!!

This is what Wikipedia had to say about waterglass or liquid glass which I have heard of being used:
Food preservation
Sodium silicate was also used as an egg preservation agent in the early 20th Century with large success. When fresh eggs are immersed in it, bacteria which cause the eggs to spoil are kept out and water is kept in. Eggs can be kept fresh using this method for up to nine months. When boiling eggs preserved this way, it is well advised to pin-prick the egg to allow steam to escape because the shell is no longer porous.
An article in The Mother Earth News offers test results for this and other methods of preservation.

Could be the same stuff

Hi, hope you are still active?

I have a jar of KePeg, and have often asked people of its uses. I have been told by many older folk that this was used to preserve eggs for 6 - 12 months. hope this helps.

Waterglass and the KePeg stuff are different.  Waterglass is actually liquid that the eggs are submerged in and the KePeg is a compound you wipe on the shells.  Both create a barrier to keep the egg from dehydrating and blocking bacteria from entering.  Have not used either, but I'd be curious since I read the longest KePeg has kept an egg usuable is 3 YEARS!!!!! OMG!
