Early results for my second year:
Normally, I only make three kinds of eggs- hard boiled, scrambled and omelets. I'm not a baker, so I can't comment on how water glassed eggs work there.
I pulled a dozen eggs from my stash a few days ago. They were all 6-7 months old. One was cracked. I knew from previous experience that one would have a strong lime taste, so I tossed it. I made scrambled eggs and they were fine.
Last year, I only made scrambled eggs and omelets (good) and over easy (burst yolks). This morning, I decided to try hard boiling 5 eggs.
Three of them cracked, two slightly and one ejected a major part of the white and yolk. It was basically a poached egg. Not my favorite form and it really messed up the water with the other eggs, but it was quite edible. I also tried a cracked HB egg. It had allowed in some water and was slightly watery, but was otherwise fine.
My bottom line:
Water glassed eggs lose a bit of structure/strength over time, but that doesn't affect taste. I've had about a 10% loss rate due to cracking and lime infiltration. They work well for scrambled/omelets, but only a percentage will give ideal results for sunny side up/over easy or hard boiled. I believe they would work well for poached and baking, but can't really comment there.
I expect to continue using this system, but will better understand and work within it's limitations in the future.
Edit: The only other long-term preservation system I would consider is freezing. I understand there are also some limitations there. For example: You remove the eggs from the shell before freezing, so there won't be hard boiled eggs. It may or may not have a loss rate, but I don't have extra freezer space, so water glassing is a very good, inexpensive, no energy alternative.
