How I use Sea Glass with Porcelain Jewellery and Ceramic!

I love to work with sea glass. After years of practise I have perfected the art of combining both sea glass and ceramic to create beautiful jewellery and ceramic art that I pride my business on. In this post I will explain how I go about making my work with sea glass.

What makes Sea Glass different from ordinary glass?

So Sea Glass begins as normal shards of broken glass that are then persistently tumbled by the oceans currents and ground until the edges are smoothed and rounded. In this process, the glass loses its shiny surface and gains a frosted appearance over many years. This process can take up to 100 years for the glass to be properly processed into Sea Glass.

Where does Sea Glass come from ?

Who knows. The ocean is a powerful force of nature and can carry materials from one side of the world to another. So no one can really know where the Sea Glass has come from. Sea Glass could have originated from broken bottles, broken tableware, antique medicine bottles or even shipwreck, its truly amazing and exciting to think about.

Different colours of Sea Glass

There are many variations of colour when it comes to Sea Glass. Each colour has an interesting history of its own, but I'm going to talk about my own experience with using coloured Sea Glass.

After using Sea Glass with Porcelain Jewellery and Ceramic I have discovered that once fired at high temperatures, Sea Glass can actually change colour. For example, I have found that the more modern brown Sea Glass turns cloudy white once fired at high temperatures. Yet, old brown Sea Glass stays the same colour once fired. The reason for this is the chemical differences. Sea Glass is very unpredictable. Old or new, Sea Glass before firing looks the same. So only when the Sea Glass has been fired does it reveal some of its history.

How it works.

Once I have made a piece of Porcelain Jewellery, I then find a piece of Sea Glass to perfectly fit the Porcelain piece, this is important because if the Sea Glass is too big or too small it will ruin the jewellery.

I then place the Sea Glass onto the Porcelain and place it into the kiln. It is then fired at a high temperature and then carefully cooled down.

If the Jewellery cools too fast, it can break. And if the jewellery is cooled too slow, the Sea Glass can bubble and become sharp.

If fired correctly the Sea Glass liquifies and fuses into the Porcelain and then reforms into a smooth body of glass. The Porcelain piece and Sea Glass essentially become one, and create beautiful and unpredictable colours.

Sea Glass is truly a beautiful thing and so full of history. I love that not only can I preserve a piece of history in wearable jewellery but I can repurpose Sea Glass that might not otherwise be used.
