Pearl buttons are cooler than plastic, and not just because they bring a tiny gleam to the dresses and shirts onto which they’re stitched. If you put your pearl button up to your cheek and then do the same with a plastic one, you’ll notice an actual difference in temperature.

That’s just one of the things I learned when I visited the Pearl Button Museum in Muscatine, Iowa. I also discovered that pearl buttons are heavier than plastic, and that they make a different sound as they slide through your fingers.
As a transplanted Californian who spent her childhood obsessively collecting shells, I’d always assumed that lustrous, white mother-of-pearl buttons came from the ocean. But there was a time when 37 percent of the world’s buttons (in 1905, that was 1.5 billion buttons) came from the glossy inner surfaces of freshwater mollusk shells harvested by citizens of this small town on the Mississippi River.  

Muscatine’s downtown today is a sleepy place Button_counter.jpgwith brick buildings on a quiet main street just a block from the river. The Pearl Button Museum isn’t large: on a single floor you can see the flat-bottom boats used to harvest mussels and the machinery to cut, drill, and polish the button “blanks.” You can try your hand at sewing buttons on a card, dip your fingers in buckets of buttons, and count out a gross (144 buttons) with a specially indented wooden paddle.  

Historical photos provide insight into a town in which half the workforce (including many children) contributed to the button industry. After the mussels were collected — a process known as clamming — men and women worked in camps along the water heating and opening the mussels, removing the meat and any irregular-shaped freshwater pearls (called “slugs”) they were lucky enough to find. Hundreds of men worked in the cutting shops, cutting blanks — the basic shape of the button — from the shiny inner surface of the shells, while others operated machinery that carved designs on the blanks and drilled the holes.

Women shaped fancier buttons against rotating emery wheels and removed the dark surface or “bark” on buttons by machine; sorted buttons by color, iridescence, and size; and sewed them onto cards. The dozens of factories in town ranged from the Hawkeye Button Company, that once employed 800 people and had offices in New York and St. Louis, to myriad mom-and-pop operations.

Button_cut_shell.jpgThe riverbanks and alleys of Muscatine were piled high with leftover shells. Tons were crushed to create street surfaces, fertilizer, stucco, and even gravel for the bottom of fish bowls. Kristin McHugh-Johnston, director of the Muscatine History and Industry Center, said that even today, when she’s working in her garden eight blocks from the river, she sometimes digs up a shell from which buttons were cut.

While Muscatine takes pride in its button heritage — a 28-foot tall bronze sculpture of a “clammer” hoists his clamming forks above the downtown riverfront — the museum displays acknowledge that creating these pearl lovelies was a dirty, dangerous, and low-paying business. Advances in button-making machinery ensured Muscatine’s reign as the “Pearl Button Capitol of the World” for decades, but eventually Mississippi mussels were fished to scarcity and freshwater and ocean shells were shipped to Muscatine for cutting. Plastic buttons, zippers, changes in fashion, and foreign competition led to a decline in the industry. The last Muscatine pearl button was cut in 1967, though production began to slow in the 1930s. There are just three button companies in Muscatine today, all producing plastic buttons and other plastic products.Button_etsy1.jpg

Most pearl buttons now are made in Asia from clam, mussel, agoya, and abalone shells. Designs are cut with lasers and dyed buttons often receive a polyester coating to protect their surface. Elaborate fusions of rhinestones, plastics, and pearl create elegant buttons, unimaginable in Muscatine’s pearl button heyday.

Still, when I’m at a flea market or antique shop and happen upon those simple, shiny vintage disks, I feel a thrill of pleasure: finding a Blue Bonnet or Lucky Day brand button card adorned with a drawing of a laughing baby or the placket of a manly shirt reminds me of all that I’ve learned about pearl buttons (and about my adopted state). The cool surface of the lustrous discs assures me that this is the real thing
