Have you ever dreamed of discovering buried treasure? You can – in Seaham, a rejuvenated English harbour town on the Durham Heritage Coast that’s well worth a visit. Finding beautiful Seaham sea glass here is as easy as waiting for the tide to turn on the world-famous Seaham Beach.

Seaham Beach has a strong reputation among sea glass collectors who flock to this rejuvenated former mining and industrial town on England’s Northern coast to explore the beaches at Seaham and to search for Seaham beach sea glass!

Why Seaham Sea Glass?

Growing up on a small island, I spent hours beach-combing for sea glass gems. Most of the time, there was a lot of hunting and very slim pickings! So, after moving to Yorkshire, I searched for where to find sea glass near me and realised I could visit the best beach with glass in England – Seaham Beach!

Where is Seaham England?

Seaham is a coastal town in County Durham, England. Located on the amazing Durham Coast, Seaham is situated 6 miles south of the city of Sunderland and 13 miles to the east of the historic city of Durham

What is Sea Glass? 

Sea Glass (or beach glass) is the name given to glass that has been dumped into the world’s seas and oceans. Over time, the glass is tumbled and shaped by the sea, before washing up onto the shore. It’s the ultimate recycled glass!

Where does Sea Glass come from?

Sea Glass washes ashore on beaches all around the world. However, it’s the quantity and the colour variations of sea glass on the beach at Seaham that make it so popular with visiting sea glass collectors.  Some other good beaches for seaglass in the UK include Marazion Beach in Cornwall and Lulworth Cove in Dorset, near Durdle Door.

Seaham Sea Glass History

The steep and exposed path down to the famous Seaham sea glass beach

Seaham was once home to the largest glass bottle works in Britain. The Londonderry Bottleworks, operated until the early 1920s, producing up to 20 million hand-blown glass bottles a year at its peak. Made in different colours and designs, glass bottles from Seaham were shipped all around the world.  

As part of the manufacturing process, however, waste glass was dumped straight into the North Sea. That’s what makes Seaham such a treasure trove for sea glass collectors today. Twice a day, on every new tide, the beaches at Seaham are sprinkled with shiny new glass gems, that have been tumbled, smoothed, and speckled by the North Sea for decades.  

What is Seaham sea glass like? 

Every sea glass pebble is a unique shape and colour, with individual markings. At Seaham, you’ll discover lots of different colours and types of sea glass, including codd marbles, which were used as a seal for carbonated drinks. There’s also safety glass with wire reinforcements still running through it, bottlenecks, and sea pottery! 

The most common sea glass to find in Seaham is clear and green glass – this was the most popular glass produced by the Londonderry bottle works. If you’re lucky, you might also find yellow, red, blue, aqua, and even multi-coloured pebbles or milk glass in pastel shades of blues, yellows, and green. It all depends on what the tide washes in! 

Fun fact: If you find black glass, you’ve found some of the oldest glass produced by the bottle works!

Seaham has several beaches, with varying quantities of sea glass on the beach, however, the most popular beach for finding Seaham Sea Glass is Seaham Beach (known as Seaham Hall Beach until 2013). Seaham Beach is also known locally as North Beach or Vane Tempest.  

How to find Seaham sea glass

You can spot Seaham sea glass at any time during low tide; however, some hunters choose to follow the sea out a few hours after high tide. With every wave new sea glass is washed up onto the beach and snatched back, never to be seen again. 

The beaches at Seaham are sand and shingle, which can make sea glass tricky to spot. What you will probably see is sea glass hunters using one of two techniques:

  • “The stooped walk” – walking along slightly bent over, to scan the beach for sea glass on the surface
  • “The diggers and rock turners” – using a small spade or stick to delve beneath the surface for buried Seaham sea glass

Don’t forget that the beach changes with every tide – especially after a big storm!

What can you do with sea glass?

Here are a few ideas of what to do with beach glass:

  • Display the sea glass in pretty glass bottles or bowls
  • Create stunning jewellery
  • Make a picture from the sea glass

Of course, if you’re lucky enough to find a large piece of red sea glass, you could also sell it! Red is the rarest, most sought-after sea glass colour! 

A Responsible Tourism Note – Sea Glass Collecting

Currently, there are no restrictions on how much sea glass you collect from the beach at Seaham, unlike many other famous sea glass beaches worldwide. Some even ban any beach glass collecting at all!

While it’s lovely to take a small amount of beautiful Seaham sea glass home to enjoy, it’s thoughtful to leave some behind for others to discover.

Seaham Lighthouse

Seaham harbour is protected from storms by two long breakwaters, with the town’s lighthouse being built in 1905, right at the end of the north breakwater. The 10-metre-high lighthouse has a cylindrical metal tower which is painted in an alternating black-and-white pattern

A real favourite with photographers, Seaham lighthouse, is spectacular to see when high winds cause waves to crash over it.

Safety Note: When built, the breakwaters in Seaham had railings – these were removed years ago, so take care if you plan to walk along them!

Blast Beach

Blast Beach is blooming again today, thanks to a massive clean-up partnership involving the National Trust. If you’re up for a scramble down to (and back from) the beach, there’s sea glass here too.

Blast Beach was once the infamous home of the biggest coal mine in Europe, with some of the worst coastline pollution in the world. The natural beach lay buried beneath the two and a half million tonnes of toxic waste from Dawdon colliery that was dumped here every year. It was an ecological disaster for wildlife and a real no-go zone for human visitors too. 

Fun fact: Eagle-eyed movie fans will spot that part of Blast Beach was used in the opening sequence of the Alien 3 movie!
