As an egg ages, its shell turns into extra porous, permitting moisture to evaporate and the shell to develop into rougher. Moreover, cracks or dents within the shell can expose the internal egg to micro organism and enhance the danger of spoilage.
| Texture | Situation |
|---|---|
| Easy, even | Contemporary |
| Tough, porous | Older |
| Cracked or dented | Unsafe to eat |
Eggshell Colour

The Skinny Albumen Layers
Along with the chalaziferous layer, the internal skinny albumen, and the outer thick albumen, there are two extra skinny albumen layers. These layers are positioned on the skin of the egg, between the shell and the outer thick albumen. These skinny albumen layers assist to guard the egg from contamination.
| Albumen Layer | Perform |
|---|---|
| Chalaziferous Layer | Retains the yolk in place |
