Nothing much new under the sun!

During the 39-45 war, eggs were more seasonal with a glut in spring and none later, as the hens were slaughtered for meat and to save on feedstuff. We used to preserve the new-laid eggs by dipping them into an aqueous sodium silicate solution, This formed a glassy surface to the shell, stopping the ingress of bacteria. The eggs would keep reasonably well for many months.
