Remember the days of swapping holiday candy with your classmates in school? We're thinking about those chalky heart-shaped candies in particular. Conversation hearts.

The history of Sweethearts

The very first conversation heart was created in 1866 by a man named Daniel Chase. Daniel made a machine that pressed food dye letters onto candy lozenges made famous by his brother, NECCO founder Oliver Chase. Oliver created these lozenges as a pharmacist looking to get in on the apothecary lozenges craze as a remedy for sore throats or bad breath, according to Mental Floss.

The candy gained popularity with the name Sweethearts and over time, the candy sayings have changed based on pop culture. From mid February to January the company produces about 100,000 pounds of candy hearts each day.

Sweethearts have evolved over time and can now be bought in a variety of versions: in Spanish, tart flavor, sugar-free and chocolate.

The sayings

The original candies had messages like, "Who Me, Luv U, Be Good, Kiss Me and Sweet Talk." Fast forward to present day and you can find hearts with sayings like, "Wicked Cool, Txt Me, Tweet, #Love, Wink Wink, Ur Hot, Call Me and even Marry Me."

Those sayings not good enough? You can make your own. Personalized custom conversation love heart candies and mints are totally a thing. Not quite what you're looking for? even sells bible verses with references from John 3:16. You'll find sayings like, "God Loves You," "Praise God," "Faith, Hope, Love."

The sayings have truly evolved over the years. During anniversaries NECCO brought back a few of the old sayings that were once popular. Go here to see 10+ years of conversation hearts.
