What is Eggshell? An informational overview

Eggs are one of the few foods that should be classified as “superfoods.” Generally, eggs are thought to be a dairy product, but they are not dairy like other items, including yogurt, milk, and cheese.  They are loaded with nutrients. The hard, outermost covering of an egg is known as the eggshell. It contains mostly calcium in the form of calcium carbonate. The inner portion is made up of mainly protein and minerals.

Composition of eggshell:

The outer covering of an eggshell is composed of CaCO₃ (Calcium carbonate), which is known as calcite, and the inner shell membrane.
About 9–12% of an egg’s weight is made up of its shell, and when considering an eggshell’s chemical makeup, 98% of it is made up of dry matter, and 2% is water. The two main components of dry matter are crude protein (5%) and ash (93%).

Microscopically, eggshells are made up of a network of protein fibers that are connected to calcium, magnesium carbonate, and calcium phosphate crystals, as well as a few other organic materials, including water.
