Seaglass, sculpture & history in Seaham, UK

The beaches at Seaham have such a strong reputation among sea glass collectors that fans of sea glass flock to this rejuvenated former mining and industrial town on England’s Northern coast. Seaham seaglass is highly prized!. 

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 knew I had to visit the best beach with glass in England – Seaham!

What is Sea Glass? 

Sea Glass (or beach glass) is the name given to glass which 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 makes it so popular with visiting sea glass collectors.  

Why is there so much Sea Glass in Seaham?

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, bottle necks 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 I 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

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 was 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 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. 

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.

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

  1. This totally reminds me of a place on the coast of Oregon in the US where you can find beautiful glass. They have a festival every year and all the products that the local artists create are magical!

  2. As a little girl, we used to look for sea glass every time we were on the beach. We didn’t often find it, but that didn’t stop us looking. I like the sound of Seaham and will have to take a stroll there while not making it obvious that I am glass hunting.

    1. Hi Larch, how lovely to hear that you’ve also been bitten by the sea glass collecting bug! Seaham is really lovely and I’m sure you would enjoy a visit there 🙂

  3. I love pebbles on beach and therefore this glass beach at Seaham looks really beautiful. I have never seen sea glass and therefore it would great to see these transparent pieces with blue sea. Good to know that they are recycled glass. I loved your ideas on how to create some art work with those glass pieces. It would really look good on tabletop or sticking them as border of photo frame.

      1. Hello Coralie

        Thank you for accurate description of our little home town. (the bus numbers have inevitably changed) Larch need not be concerned about looking like a sea glass hunter. Most of our visitors are doing the same and we don’t mind. When I was a boy in the 1950s the beaches were our playground, between tides, and the sea glass was everywhere amongst the pebbles. We just used to let it lie there but I see that it is now appearing in artwork on a site called “ETSY”

        best wishes

        1. Thanks for taking the time to comment Ian – how lovely to have a view from a real local. I loved exploring Seaham and delving into the fascinating history. I did collect a few lovely glass pebbles – but not to sell on Etsy 🙂

          Best wishes

  4. Oh, you’re speaking to my heart now! I grew up on the shores of Lake Erie in the U.S. and beach glass was always a treasure to find and so relaxing to search for. I pinned this post to save for when I go to England. This makes me want to go even more now. Thank you!

    1. Hi Nancy, there is something quite magical isn’t there about finding those little glass gems tucked into sand or shingle? I hope you do get to visit Seaham when you come to England, as it’s a lovely little town 🙂

  5. My 16yr old just fell in love with beach hunting last year and when the pandemic hit the US and shut down school she became more interested. This past Christmas, I gifted her a trip to Seaham for her high school graduation in 2022. We are so excited. Thank you for this article. It’s helped start our search of other things to see…if it’s possible to pry us away from the beach hunting. :))))
