Nantgarw & Swansea Porcelain

The production of fine Welsh porcelain as opposed to Welsh pottery lasted a very short time - from 1813 to 1826. Swansea pottery had a far longer history, having been produced on a much larger scale for over one hundred years. Both Swansea pottery and porcelain are connected as the works were on the same site. The Nantgarw porcelain factory is also closely tied with the Swansea manufacturers because the production experiments at Nantgarw influenced the later techniques in Swansea. Also, one gentleman had the greatest influence over both factories.

The man behind Welsh porcelain was William Billingsley. Born in 1758, he was initially the leading botanical decorator at the Derby porcelain factory. Then in 1813, in the village of Nantgarw on the River Taff, six miles north of Cardiff, Billingsley established a porcelain works, which within a year was producing superb soft-paste porcelain. In fact, academics say that the quality in terms of colour and translucency, was bettered only by Sevres in France. It is also assumed that the quality has not been surpassed in Britain since.

The production of such high-quality porcelain at Nantgarw was costly and much of the porcelain suffered kiln collapse, thus Billingsley encountered considerable financial loss. As a result, it was necessary for him to introduce new partners to the business, notably William Weston Young and Lewis Weston Dillwyn. Dillwyn moved the production to Swansea, with the aim of becoming more commercially viable, and to attempt to stabilise the erratic unreliable Nantgarw porcelain formula. So, from 1814, porcelain was produced at the site of the Cambrian pottery works in Swansea (located where Swansea High Street railway station is now).

In 1818, William Billingsley left Swansea and returned to Nantgarw to reopen the works with the aim of producing the highest quality porcelain for the top-end of the London market. His desire was for it to be decorated by the esteemed London decorators of the time. Indeed, his plan worked to some extent as the porcelain that was produced was again exquisite and was in demand from the upper classes, it was also a success in that most Nantgarw porcelain was decorated in London for the London market, with only a small proportion decorated locally (the reverse is true for the Swansea operation - with a smaller proportion of items decorated in London).

However, the quality of Nantgarw porcelain still came at a high cost and the high rate of failure in the kiln continued, meaning that again, sadly for Billingsley, the venture at Nantgarw was not commercial. In 1823, the Nantgarw factory closed (apart from a small works for utilitarian products such as tobacco pipes – which lasted until about 1920). To recover some of the investment in the Nantgarw business, Thomas Pardoe was employed to decorate the remaining undecorated Nantgarw stock, it was then sold off at auctions in 1821 and 1822.

In Swansea, the production of porcelain was more viable, they were able to produce a more stable reliable porcelain. However, the factory was taken over by the Bevington Partnership in 1817 and reverted to producing pottery. When the porcelain production was ceased, they continued to employ some of the decorators to work on remaining undecorated stock. Similarly, to Nantgarw, this remaining stock of Swansea porcelain was sold by auction in January 1826.

How is Swansea and Nantgarw porcelain perceived today?

Even to the non-collector of porcelain, the quality is admired. When we hold pieces up to a strong light we can see directly through the porcelain as though it is glass. Anyone who enjoys fine art can admire the precise and beautiful decoration. The flora, fauna, landscapes, and figures are of the finest quality with some items decorated by the best artists of the age.

Some of the porcelain was decorated to be an individual unique item, other pieces were fashioned in set patterns influenced by the taste of the day. Some of the hand-painted sets relate to commissions by wealthy landowners or aristocracy – such as the Duke of Cambridge service and the Burdett Coutts service. This gives items impeccable provenance and adds to the fascinating history of these wonderful objects.

The highest standards of quality porcelain did not diminish in the short time that Welsh porcelain was produced. This very short time span of high-quality production from both the Swansea and Nantgarw factories gives Welsh porcelain ‘The Beatles’ factor for collectors, it also means that Nantgarw and Swansea porcelain is rarer than most comparisons from Staffordshire, Derby and Worcester porcelain.

The other unique selling point is that it is all Welsh, of course. It is a Welsh story and it is incredible to be able to say that possibly the finest porcelain in the world was produced in Wales – albeit for a short time. Welsh porcelain really does attract patriotic Welsh collectors and many of these collectors are still thirsty for more knowledge, rarer items, and additions to their collections.

The Market

The market for Welsh porcelain had seen a period of deterioration in the last decade. Speaking to the collecting base, one of the reasons for this was that vendors felt that South Wales lacked a specialist outlet for such items, they were instead going to the London salerooms to be auctioned. There was a time that these London salerooms did have outlets in Wales, but in their focus on emerging international markets and the million-pound deals, most provincial salerooms and offices were closed.

As a result, the market for Welsh porcelain suffered, because most, not all but most, of the collecting base is located here in South Wales, not near London. The nature of these collectors is that they much prefer to view the porcelain in person, they want to handle the items before they buy, examine the fineness of the porcelain, and study closely the decoration. Yes a few of these collectors were prepared to travel to London to view some of the more important lots, but many felt that their requirements were no longer catered for - some collectors just didn’t know auctions were happening, while others lost interest and stopped collecting altogether.

So, while the collections and individual items began traveling down the M4 to auction rooms, the market dipped. As a response to this drop, the London salerooms began a strategy of dispersing collections to other locations, with good bread and butter Welsh porcelain items, entered by vendors in Wales, ending up in obscure locations to be auctioned.

We can say with confidence that The Welsh Sale - our three times per year specialist auction of all things Welsh, has become the ideal platform to sell Welsh porcelain. We now have the results to demonstrate:

- Since 2013, ten out of thirteen lots of Swansea porcelain that have made over £2,500 at UK auctions (at around 300 auction rooms), were sold through us at The Welsh Sale

- Since 2013, of the twenty-eight lots of Nantgarw porcelain that have made over £2,500 at UK auctions, seventeen of those were sold at The Welsh Sale

This data can be seen on whom collate and manage auction records.

We feel strongly we have reinvigorated the market for this culturally important sector. By offering the porcelain in a prestigious Welsh driven auction, we have encouraged the patriotism that goes hand in hand with collecting, we have brought the established collectors from England and Wales to the saleroom for our Welsh Sale, while we have also encouraged new collectors into the market by showing off these beautiful ceramics in the same fully illustrated catalogue as fine Welsh paintings and Welsh antiques. We are confident that all the important collectors of Welsh porcelain – whether they be private individuals or organisations, now receive these superb catalogues.

To further enhance the buying experience of porcelain at The Welsh Sale, we have professional illuminated showcases at the saleroom and the lots benefit from quality multiple digital images.

What is even more pleasing is considering the original North Wales background of our company, we are now selling some of the porcelain to our North Wales collecting base who have developed a taste for it through The Welsh Sale. It is very rewarding to see renewed interest in this important element of Welsh history and fine art.
