The organic matter of an egg shell contain proteins, carbohydrates, lipids, Uronic acid, calcium carbonate (94%) and magnesium carbonate. It is this combination of minerals that produce a hard shell.

A soft egg becomes hard primarily through the process of cooking, which involves heat denaturation of the proteins in the egg whites and yolk. When exposed to heat, the proteins unfold and then coagulate, transforming the liquid egg into a solid form. This process occurs at different temperatures; for instance, soft-boiled eggs typically set at around 70-80°C (158-176°F), while hard-boiled eggs require temperatures above 90°C (194°F). The longer the egg is cooked, the firmer its texture becomes.
Frozen, hard boiled is like soft rubber
A hard boiled egg is cooked until solid all the way through, a normal 'soft' boiled egg the centre yolk will still be runny, To test the egg you need to do is spin the egg on a flat surface, if the egg is soft boiled it will wobble because part of the egg is still liquid, if it is hard boiled it will spin on end, because the contents are solid.
Turtle eggs (and tortoise eggs) can be either hard or soft-shelled, depending on the species.

A hard boiled egg is made of..... egg. It is simply a whole egg, in the shell that has been placed in boiling water. The heat causes the liquid egg inside the shell to become solid. The yolk of the egg becomes the yellow center, and the clear "white" of the egg becomes the white outer part of the boiled egg. Remove shell, add salt to taste, eat.
