During the Renaissance, young Italian gentlemen filled empty eggshells with perfume and tossed them at women as a sign of their affection. This custom spread to Spain, France and Austria and then crossed the Atlantic. In Mexico, Carlotta was the wife of Emperor Maximillian. Empress Carlotta is said to have filled empty eggshells with confetti instead of cologne. The confetti-filled eggs were used for Easter celebrations and other fiestas.

In the Spanish language, cascaron means "eggshell". There are many styles of cascarones made in Mexico today. Some are very simple and others are painted fancy or modeled to look like animals and other designs. Sometimes, the decorated cascarones are placed in tall paper cones. Today, children "bump" the cascarones on the heads of family and friends and make a wish. If the egg breaks and covers the person with a shower of confetti, the wish is supposed to come true.
