Made by man, finished by nature: Now's the best time to hit the beach to hunt for sea glass

Once part of a whole object, it has become its own entity: sea glass.

These pieces created by humans for function have been reclaimed by water, tossed by the lakes and seas and given back to us as fragments of beauty. And now as the weather warms, beachside residents are blessed with the possibility of days spent by the beach hunting sea glass.

But what do you look for? How do you get started? What colors should you seek? How do you turn it into decor or jewelry?

To help out, we've put together this sea glass primer:

Pure sea glass consists of pieces that have broken apart from lanterns, headlights, bottles and other glass items that were dumped or thrown into lakes and oceans. Over 15 to 60 years, and sometimes for more than a century, the forces of waves, sand and stone have rounded the sharp edges of these glass shards to create smooth, translucent shapes.

Sea glass is best found on pebbly or stony beaches about 10 feet from the water line. "You will almost never find sea glass on a sandy beach," says Cindy Kuhn, 55, of Columbus, Ohio, a jeweler who has been collecting sea glass for five decades. She adds that it's wonderful to go hunting "after a storm because water gets churned up."

Linda Mickevicius, 56, has been collecting sea glass along Michigan's shores for the past seven years. She recommends looking for "a nice gravel wash along the shore."

Like several sea glass fanatics, she's reluctant to give away the exact locations of where she collects, but she recommends looking around the shores of Sawyer and Lakeside, Mich. Also try Lakeside Beach to Conger-Lighthouse Beach in Port Huron, Mich.

The shores of Lake Erie, where Kuhn began collecting as a young girl, are also rich in sea glass.

One of the most famous sea glass beaches in America is Glass Beach in Fort Bragg, Calif., which was once a public dump and is now covered with sea glass. Visitors must only admire, though, because California State Parks has taken over the site and prohibited collecting.

Sea glass colors serve a purpose beyond aesthetics. Sea glass colors matter because they signify rarity. Kuhn and Mickevicius, both active members of the North American Sea Glass Association, say orange is the rarest color. Kuhn says orange glass could have come from decorative glassware like goblets, candy dishes and decanters.

Pinks, reds and yellows follow as the next rarest. After that comes kiwi and lime green, lavender, sky blue and turquoise. Next come cobalt blues. The most common colors are kelly green, rich brown and white _ not just because of beer bottles but also because of old medicine and bleach containers.

Comparing artificial to pure sea glass "... is like comparing cubic zirconia to a diamond," Kuhn says. "It's very distressing to see people pay a lot of money for a fake piece of sea glass." The best way to establish that what you have is pure is to pick it out of a lake or ocean on your own. Other than that, Kuhn says to look for pure sea glass to have rounded edges and frosting, as well as small, naturally formed C-shaped pits that are difficult to duplicate.

A simple way to make sea glass into jewelry is to turn your finds into pendants. Robin Servo, a jewelry and metalsmithing instructor at the Birmingham Bloomfield (Mich.) Art Center, did a recent drop-in workshop where she and the students affixed wire to artificially tumbled sea glass and formed a loop so the glass could be hung on a leather or metal chain.

Expert sea glass jewelers like Mickevicius and Kuhn can also integrate sea glass into bracelets, earrings and rings. Other than jewelry, people have used sea glass in mosaics, suncatchers, candleholders and ornaments. Others use jars to compile their handfuls of sea glass, each vessel serving as decor with a story.

BEST PLACES TO HUNT FOR SEA GLASS

Historically active waterfront sites, known to have shipping traffic.

Areas where shipping channels come close to shore or where small boat traffic is active.

Shorelines that receive the prevailing winds of the region (primarily northwesterly in Michigan).

Locations along the shore where locals discarded household items years ago.

Shorelines with an abrasive surface at water's edge that often experience strong onshore winds. (Moving water and rough terrain create ideal conditions.)
