egg shells

Calcium-rich breakfast waste

The hard, brittle outer covering of an egg, composed mainly of calcium carbonate.

Eggshells protect the developing embryo and are discarded after the egg is cracked open.

Crushed eggshells find use in gardening as soil amendment.

To walk on eggshells is to act with extreme caution to avoid upsetting someone.

Also spelled as one word: eggshells.
