International Sea Glass Association Festival

2023 Sea Glass Festival

The International Sea Glass Association is pleased to announce its return to New England by hosting the 17th Annual Festival on the Village Green of the Mystic Seaport Museum in Mystic, Connecticut. The Festival will take place on Saturday and Sunday, July 29–30, 2023, from 10 a.m. to 5 p.m.

The International Sea Glass Festival is the premier sea and beach glass event in the country celebrating the history and beauty of genuine sea and beach glass.    

A summer visit to the nation’s number one maritime museum, talented artists and craftspeople, knowledgeable speakers, the sea glass contest, and an opportunity to connect with fellow sea glass enthusiasts will make for an unforgettable weekend. Admission to the Museum covers admission to the Festival, and a one-day ticket can be validated to enter a second day to enjoy the Museum and the Festival to its fullest.

We are looking for sea and beach glass collectors who would like to have a table in the marquee tent on Saturday and Sunday, July 29–30, 2023, from 10 a.m. to 5 p.m.

Zen Sea Glassing

Saturday, July 29, 2023, 11:30 am

Guy Fleming

In a lifetime, change may occur quickly and sometimes very unexpectedly. After Guy lost all his worldly possessions in the severe Superstorm Sandy of 2012, he faced  another tragedy when he divorced shortly afterward. Searching for solace and new beginning in life, he began walking beach, discovering sea glass and an improved quality of life. Guy will share personal stories, Zen techniques and important ways to become an environmental steward.

Guy Cash Fleming has been expressing himself creatively ever since he sat down with a bass guitar as a teenager. He spent 34 years working as a chemical operator and instrumentation technician for a major pharmaceutical company, and he is also a musician, photographer, and amateur sea glass jeweler. Although he thought he’d never write a book, six months into retirement he suddenly had the urge and honored it wholeheartedly, with the release of For the Love of Sea Glass. Since then he’s walked more than 10,000 miles on the beaches of New Jersey, found in excess of 200,000 pieces of sea glass, and wrote two additional books, entitled Sea Glass for Miles, (a sea glass color/rarity guide), and Sea Glass Stories from the Beautiful New Jersey Coast, a coffee table book. Guy lives in New Jersey with his wife Yolanda, also an author, and their two young adult children.

Sailing for Sea Glass

Sunday, July 23, 2023, 11:00 am

Ky Davis

Captain Ky Davis lives on a Ta Yang (Tayana) 50′ Flying Dutchman sailboat and travels the Caribbean in search of rare sea glass. Ky will share some of his experiences hunting for sea glass on beaches, in underwater caves, and down cliff sides, where he finds beautiful, rare sea glass and more. You’ll get a peek at his life living on his sailboat as he travels the seas to find untouched sea glass beaches.

Captain Ky the Sea Glass Guy from LC’s Glass is a treasure hunter circumnavigating the world on his sailboat, The Emerald of Pleiades, with his Yorkshire Terrier, LC, in search of the world’s greatest unknown sea glass beaches. He has spent time as a firefighter, combat medic, explorer, adventurer, survivalist, farmer, and ship captain.

A History of Maritime Mystic

Saturday, July 29, 2023, 2:00 p.m.

Rich Froh

Mystic has long been a major hub of the seafaring world, playing host to shipbuilding, fishing, global trade, naval warfare, and everything in between. Come learn about our rich local history, and discover what makes Mystic such a special place.

Richard (Rich) Froh has spent his life exploring local waters and waterfronts and feeding his hunger for history, especially local and maritime histories. With his wife, June, Rich has traveled to many historic sites in the U.S. and Europe, but his appreciation for the history of the Mystic River area and Mystic’s connection to national and world events remains the center of his focus and passion. His full-time job at the Museum allows him to, as he puts it, “de-mystify Mystic” by helping history buffs and those less familiar with our past, appreciate what has happened on these grounds and the surrounding waters.


General Admission Tickets to Mystic Seaport Museum cover admission to the Festival for two days. Your one-day ticket can be validated for a second day. Your ticket gives you admission to both days of the festival, lectures, and the Sea Glass Contest. You can also visit the Mystic Seaport Museum grounds, including world-class exhibits such as Voyaging in the Wake of the WhalersFigureheads, Sea as Muse, and much more. Other attractions at Mystic Seaport include free planetarium shows, the Children’s Museum, the Homeport Family Activity Center, and access to the Charles W. Morgan — the world’s last authentic wooden whaling ship. You can purchase tickets on the day of the festival at the Museum or purchase General Admission tickets online. Adult $28 | Senior 65+ $26 | Youth 13-17 $24 | Child 4-12 $19 | 0-3 free.

FREE parking is available in the lots across the street at the North Entrance.

Mystic Seaport Museum

Mystic Seaport Museum is the nation’s leading maritime museum. Founded in 1929 to gather and preserve the rapidly disappearing artifacts of America’s seafaring past, the Museum has grown to become a national center for research and education with the mission to “inspire an enduring connection to the American maritime experience.”

The Mystic Seaport Museum grounds cover 19 acres on the Mystic River in Mystic, Connecticut, and include a recreated New England coastal village, a working shipyard, formal exhibit halls, and state-of-the-art artifact storage facilities. The Museum is home to more than 500 historic watercraft, including four National Historic Landmark vessels, most notably the 1841 whaleship Charles W. Morgan, America’s oldest commercial ship still in existence.
