Broken egg shell,coloured scanning electron micrograph (SEM). Hard-shelled eggs are produced by birds and some reptiles. The shell protects the embryo inside,and controls the passage of air in and out of the egg through tiny pores. Most of the egg shell material is calcium carbonate,and accounts for about a tenth of the egg's weight. This egg shell is from a chicken's egg.
